Dark Energy and Dark Gravity

Observations provide increasingly strong evidence that the universe is accelerating. This revolutionary advance in cosmological observations confronts cosmological theory with a tremendous challenge, which it has so far failed to meet. Explanations of the acceleration within the framework of general relativity are plagued by difficulties. General relativistic models are nearly all based on a dark energy field with fine-tuned, unnatural properties. There is a great variety of models, but all share one feature in common-an inability to account for the gravitational properties of the vacuum energy. Speculative ideas from string theory may hold some promise, but it is fair to say that no convincing model has yet been proposed. An alternative to dark energy is that gravity itself may behave differently from general relativity on the largest scales, in such a way as to produce acceleration. The alternative approach of modified gravity provides a new angle on the problem, but also faces severe difficulties, including the problem of explaining why the vacuum energy does not gravitate. The lack of an adequate theoretical framework for the late-time acceleration of the universe represents a deep crisis for theory-but also an exciting challenge for theorists. It seems likely that an entirely new paradigm is required to resolve this crisis.
Supercapacitor-assisted low dropout regulator technique: a new design approach to achieve high-efficiency linear DC–DC converters

Approximate efficiency of a linear regulator is given by the ratio of regulated output voltage to input voltage. Higher voltage difference between the input and the output means a lower efficiency due to heavy losses in the series power semiconductor. Supercapacitor-assisted low dropout regulator (SCALDO) is an emerging linear DC-DC converter technique, where a supercapacitor (SC) is used to reduce the voltage drop across the series transistor in a linear regulator where the SC acts as a lossless dropper. The circuit operates at a very low frequency decided by the size of the SC. An efficiency multiplication factor such as 1.33, 2, or 3 is achieved depending on the configuration. This study presents the essentials of its generalised theory, few prototype implementations, and a discussion on SCALDO properties. Typical efficiencies of 12-5 and 5-1.2 V linear regulators are around 42 and 24%, respectively. When SCALDO prototypes are built, the authors achieve respective end-to-end efficiencies of 79-81 and 58-73%. A loss analysis summary and further developments of the novel technique are also provided, in addition to a discussion to indicate that this is not a variation of the switched capacitor converters.
Optimization of X-ray beam profilers based on CVD diamond detectors

A complete beam profiler, based on a CVD diamond pixel detector, has been developed for real-time X-ray source imaging, showing good results in terms of sensitivity and response speed. A dedicated microcontroller-based read-out electronics has been designed to ensure real-time monitoring for a wide range of beam intensities and dose-rates (0.001÷1 Gy/h). The influence of two different metal-diamond interfaces (Ag and Ti/Au) on the X-ray induced photocurrent characteristics has been also investigated, in order to identify which of the two types of contacts can optimize the beam profiler performance in terms of sensitivity and spatial resolution. For this purpose, a set of measurements (X-ray induced photocurrent dependence on bias voltage and dose-rate, specific sensitivity) was carried out with a standard Coolidge tube equipped with a molybdenum target (Kα line at 17.5 keV, Kβ line at 19.6 keV).
Investigation of Through-Tenon Keys on the Tensile Strength of Mortise and Tenon Joints

A timber frame is a structural building system composed of heavy timber members connected using carpentry-style joinery that may include metal fasteners. A common variant of mortise-and-tenon joints are keyed (or wedged) through-tenon joints. No research on the behavior of wedged joints in timber frames is available. This research provides design knowledge of keyed through-tenon joints from experimental observations and comparisons between mathematical models and experimental measurement. Evaluation of through-tenon keyed mortise and tenon joints was performed by measuring tensile load and stiffness of white oak (Quercus alba) and Douglas-fir (Pseudotsuga menziesii) joints with fourand 11-inch tenons with one and two keys and comparing these results to mathematical models developed from the National Design Specification of Wood Construction (NDS), General Dowel Equations for Calculating Lateral Connection Values (TR-12), and engineering mechanics. Variables included joint species (white oak or Douglas-fir), protruding tenon length (four or 11 inches), and number of keys (one or two). Joints were tested to ultimate load, then model input specimens were cut from tested joints and additional key stock to generate inputs for joint load predictions that were compared to experimental joint load results for validation. Forty joints were tested with white oak keys and six of these joints were retested with ipe (Tabebuia) keys. Joints with four-inch tenons behaved in a brittle manner with tenon failures. Most joints with 11-inch tenons behaved in a ductile manner with key bending and crushing failures. Joint load and stiffness was similar between white oak and Douglas-fir joints. Joints with 11-inch tenons had greater load and stiffness than with four-inch tenons. Joints with two keys had greater load and stiffness than joints with one key, after normalizing joint load and stiffness responses on key width. Joints retested with ipe keys had greater load than joints originally tested with white oak keys.
The Role of Key Communication Competences in Corporate Cooperation

Currently, much attention is paid to key competences, with particular emphasis on the role and competences of humans. Therefore, the purpose of this paper is to overview the competence definitions and key competences related thereto. Moreover the paper will focus on the role of communication competences along with up to date communication technology. The typologies of competence currently appearing in Polish and international literature will also be presented. The role of cultural dimensions in the formation of relationships with international partners will be highlighted as well. The final element will include the stress put on the role of communication as one of the key competences influencing corporate cooperation and indicating the innovative forms of communication between business partners.
Excited by a quantum field: does shape matter?

The instantaneous transition rate of an arbitrarily accelerated Unruh–DeWitt particle detector on four-dimensional Minkowski space is ill defined without regularisation. We show that Schlicht's regularisation as the zero-size limit of a Lorentz-function spatial profile yields a manifestly well-defined transition rate with physically reasonable asymptotic properties. In the special case of stationary trajectories, including uniform acceleration, we recover the results that have been previously obtained by a regularisation that relies on the stationarity. Finally, we discuss evidence for the conjecture that the zero-size limit of the transition rate is independent of the detector profile.
The upgrade of the ATLAS Level-1 Central Trigger Processor

The ATLAS Level-1 Central Trigger Processor (CTP) combines information from calorimeter and muon trigger processors as well as other sources and makes the final Level-1 Accept (L1A) decision. Due to the increasing luminosity of the LHC and the growing demands of physics and monitoring placed on the ATLAS Level-1 trigger system, the current CTP has reached its design limits. Therefore and in order to provide some margin for future operation, the CTP will be upgraded during the LHC shutdown of 2013/14.
Improved vibration-based energy harvesting by annular mass configuration of piezoelectric circular diaphragms

Vibration-based energy harvesting using piezoelectric circular diaphragms (PCDs) with a structure featuring the central mass (C-mass) configuration has drawn much attention in recent decades. In this work, we propose a new configuration with the annular proof mass (A-mass) where an improved energy harvesting is promised. The numerical analysis was employed using the circuit-coupled piezoelectric simulation, and the experimental validation was implemented using PCDs with the even-width annular electrodes. Samples with the different mass configurations as well as structural parameters ϖ1 and ϖ2, which indicate the ratio between the inner boundary radius and piezoelectric ceramic radius as well as the ratio between outer boundary radius and the substrate radius, respectively, were prepared and tested. The impedance-matched output power of full-electrode PCDs was also collected, and some distinct improvement was measured on samples with the certain structural parameters. The power increases from 14.1 mW to 19.0 mW after changing the configuration from C-mass to A-mass with the same parameters (ϖ1, ϖ2) = (0.16, 0.9), showing the considerable improvement in energy harvesting by using A-mass configuration.
On analytic descriptions of two-dimensional surfaces associated with the sigma model

We study analytic descriptions of conformal immersions of the Riemann sphere S2 into the sigma model. In particular, an explicit expression for two-dimensional (2D) surfaces, obtained from the generalized Weierstrass formula, is given. It is also demonstrated that these surfaces coincide with those obtained from the Sym–Tafel formula. These two approaches correspond to parametrizations of one and the same surface in .
Personal factors affecting the audio-visual perception of the urban public space

This paper summarises a continued analysis of a previously conducted experiment with a group of 71 normal hearing participants experiencing a virtual walk along an urban bridge over a highway by means of virtual reality technology. The pleasantness of crossing the bridge for each participant was surveyed during this virtual walk. In a companioning experiment, the participants performed an audio-visual attention test. Noise sensitivity was assessed by means of a short questionnaire. The aim of this analysis was to find out how personal factors like auditory or visual dominance, and noise sensitivity, can affect the individual perception of the urban environment. The analysis of the looking behaviour during the virtual walk was compared to the results of the attention tests and noise sensitivity. Significantly different pleasantness ratings were observed for people with different attentive abilities for a scenario with an unpleasantly rated visual and shielded traffic noise. The auditory dominated participants rated the experience more pleasant than the participants that are easily visually distracted. These two groups also showed a remarkably different looking behaviour when walking over the bridge: the auditory participants turned the head to look directly at the source and during a longer time than the ones that were visually dominated. These results showed a statistically significant difference. No statistical significance was found for other personal factors like age, gender or sensitivity to noise. As a conclusion, the analysis showed the important difference between auditory and visually dominated persons, strongly impacting their appreciation of the urban environment.
SEM investigation of heart tissue samples

We used the scanning electron microscope to examine the cardiac tissue of a cow (Bos taurus), a pig (Sus scrofa), and a human (Homo sapiens). 1mm3 blocks of left ventricular tissue were prepared for SEM scanning by fixing in 96% ethanol followed by critical point drying (cryofixation), then sputter-coating with gold. The typical ridged structure of the myofibrils was observed for all the species. In addition crystal like structures were found in one of the samples of the heart tissue of the pig. These structures were investigated further using an EDVAC x-ray analysis attachment to the SEM. Elemental x-ray analysis showed highest peaks occurred for gold, followed by carbon, oxygen, magnesium and potassium. As the samples were coated with gold for conductivity, this highest peak is expected. Much lower peaks at carbon, oxygen, magnesium and potassium suggest that a cystallized salt such as a carbonate was present in the tissue before sacrifice.
A moisture and electric coupling stimulated ionic polymer-metal composite actuator with controllable deformation behavior

Ionic polymer-metal composite (IPMC) actuator can generate large and rapid deformation based on ion migration under a relatively low driving voltage. Under full hydrated conditions, the deformation is always prone to relaxation. At room humidity conditions, the deformation increases substantially at the early stage of actuation, and then decreases gradually. Generally, most researchers considered that the change of water content or relative humidity mainly leads to the deformation instabilities, which severely limits the practical applications of IPMC. In this Letter, a novel actuation mode is proposed to control the deformation behavior of IPMC by employing moisture as an independent or collaborative incentive source together with the electric field. The deformation response is continuously measured under electric field, electric field-moisture coupling stimulus and moisture stimulus. The result shows that moisture can be a favorable driving factor for IPMC actuation. Such an electric field-moisture coupling stimulus can avoid the occurrence of deformation instabilities and guarantee a superior controllable deformation in IPMC actuation. This research provides a new method to obtain stable and large deformation of IPMC, which is of great significance for the guidance of material design and application for IPMC and IPMC-type iEAP materials.
Classification of five-point differential-difference equations

Using the generalized symmetry method, we carry out, up to autonomous point transformations, the classification of integrable equations of a subclass of the autonomous five-point differential-difference equations. This subclass includes such well-known examples as the Itoh–Narita–Bogoyavlensky and the discrete Sawada–Kotera equations. The resulting list contains 17 equations, some of which seem to be new. We have found non-point transformations relating most of the resulting equations among themselves and their generalized symmetries.
DNA double strand breaks in the acute phase after synchrotron pencilbeam irradiation

Introduction. At the biomedical beamline of the European Synchrotron Radiation Facility (ESRF), we have established a method to study pencilbeam irradiation in-vivoin small animal models. The pencilbeam irradiation technique is based on the principle of microbeam irradiation, a concept of spatially fractionated high-dose irradiation. Using γH2AX as marker, we followed the development of DNA double strand breaks over 48 hrs after whole brain irradiation with the pencilbeam technique. Method. Almost square pencilbeams with an individual size of 51 × 50 μm were produced with an MSC collimator using a step and shoot approach, while the animals were moved vertically through the beam. The center-to-center distance (ctc) was 400 μm, with a peak-to-valley dose ratio (PVDR) of about 400. Five groups of healthy adult mice received peak irradiation doses of either 330 Gy or 2,460 Gy and valley doses of 0.82 Gy and 6.15 Gy, respectively. Animals were sacrificed at 2, 12 and 48 hrs after irradiation. Results. DNA double strand breaks are observed in the path of the pencilbeam. The size of the damaged volume undergoes changes within the first 48 hours after irradiation. Conclusions. The extent of DNA damage caused by pencilbeam irradiation, as assessed by H2AX antibody staining, is dose- dependent.
The effect of high pressures on the yoghurt from milk with the stabilizer

The effect of high pressures on the microbiological and physio-chemical properties of yoghurt was investigated. The best results were obtained when the yoghurt was manufactured from milk with the addition of MYO 752 stabilizer (starch, gelatin, pectin) selected from 10 stabilizers. Yoghurt manufactured with the addition of 0, 6% MYO 752 stabilizer was processed at the pressure of 400-600 MPa/15 min. in the range of 50 MPa. Pressurization caused a total reduction of number of Lactobacillus delbrueckii ssp. Bulgaricus and reduced the number of Streptococcus thermophilus by 1-2 orders of magnitude. Pressurized and non-pressurized yoghurts characterized of a homogenous consistency and typical plain yoghurt taste. The decrease of the number of living bacteria was observed in yoghurts during the storage. The acidity of pressurized yoghurts remained on the some level at the temperature of 4°C and 20°C. The more intensive antibacterial activity of microflora was observed in yoghurts storaged at 20°C in comparison with yoghurts storaged at 4°C. Disadvantageous changes of the pressurized yoghurts consistency were not found. The taste and aroma of yoghurts remained without any changes.
Insulated power supply for gate drivers up to 40 kV for medium-voltage direct current applications

The proposed study is about the design and experimental results of a power supply for gate drivers that can sustain 40 kV of insulation voltage with a parasitic capacitance of 4 pF. The first section focuses on insulation materials suitable for medium voltage capabilities and therefore to justify the use of polyesterimide and Teflon polytetrafluoroethylene materials. In a second step, experimental results are provided to guaranty that with a thickness of 1 mm of the insulation material, an insulation voltage of 40 kV is provided. Then, a DC–DC converter based on a series-series topology is designed and lead to a physical prototype of 5 W. The measured parasitic capacitance is 4 pF between the primary and the secondary sides.
Work-related contact, work–family conflict, psychological distress and sleep problems experienced by construction professionals: an integrated explanatory model

Abstract Contemporary communication technology blurs the boundaries between work–life and family–life environments, through after-hours, work-related contact. We examined the relationship between work contact, work–family conflict and consequent outcomes of psychological distress and sleep problems experienced by South African construction professionals. An integrated model of these factors was proposed and tested using path analysis and responses from 630 survey respondents. Work experience, gender, domestic situation and employment status explain the relationship between job autonomy and control, job pressures, and work contact, which were hypothesized to multivariately explain their negative effects. The final integrated model was a good fit to the data. The results indicate that the antecedents of work–family conflict are job autonomy and control, job pressure and work contact. Psychological distress is determined by work–family conflict, work experience, and job pressure. Sleep problems are influenced by work–family conflict, work contact and psychological distress. An important insight gained is the pivotal role played by job pressure, directly and indirectly, in work stress outcomes. Interventions aimed at reducing psychological distress and sleep problems among construction professionals should target the boundary permeability of work contact and work–family conflict, particularly for less experienced, female and junior professionals with low job control but high job pressure.

Efficiency improvements in US Office equipment: Expected policy impacts and uncertainties

This report describes a detailed end-use forecast of office equipment energy use for the US commercial sector. We explore the likely impacts of the US Environmental Protection Agency`s ENERGY STAR office equipment program and the potential impacts of advanced technologies. The ENERGY STAR program encourages manufacturers to voluntarily incorporate power saving features into personal computers, monitors, printers, copiers, and fax machines in exchange for allowing manufacturers to use the EPA ENERGY STAR logo in their advertising campaigns. The Advanced technology case assumes that the most energy efficient current technologies are implemented regardless of cost.
Spin-charge-family theory is offering next step in understanding elementary particles and fields and correspondingly universe

More than 40 years ago the standard model made a successful new step in understanding properties of fermion and boson fields. Now the next step is needed, which would explain what the standard model and the cosmological models just assume: a. The origin of quantum numbers of massless one family members. b. The origin of families. c. The origin of the vector gauge fields. d. The origin of the Higgses and Yukawa couplings. e. The origin of the dark matter. f. The origin of the matter-antimatter asymmetry. g. The origin of the dark energy. h. And several other open problems. The spin-charge-family theory, a kind of the Kaluza-Klein theories in (d = (2n − 1) + 1)-space-time, with d = (13 + 1) and the two kinds of the spin connection fields, which are the gauge fields of the two kinds of the Clifford algebra objects anti-commuting with one another, may provide this much needed next step. The talk presents: i. A short presentation of this theory. ii. The review over the achievements of this theory so far, with some not published yet achievements included. iii. Predictions for future experiments.
Application of additive manufacturing for mass customisation: understanding the interaction of critical barriers

Abstract Additive Manufacturing (AM) technology presents a very optimistic case for its application for mass customisation. Even though theoretically suitable, practically several critical barriers inhibit its implementation. Thus, this paper attempts to identify those barriers and also understand the dynamic interaction among them. The barriers were identified by a detailed literature review and validated by expert opinions. Interpretative Structural Modelling (ISM) was applied to determine the mutual influences among the barriers. It was also able to ascertain the level of the barriers and categorise them based on their driving power and dependence. The results are highly useful for industry practitioners to determine the interventions required to overcome the most dominant barriers.
