Holographic Mutual Information for Singular Surfaces

We study corner contributions to holographic mutual information for entangling regions composed of a set of disjoint sectors of a single infinite circle in three-dimensional conformal field theories. In spite of the UV divergence of holographic mutual information, it exhibits a first order phase transition. We show that tripartite information is also divergent for disjoint sectors, which is in contrast with the well-known feature of tripartite information being finite even when entangling regions share boundaries. We also verify the locality of corner effects by studying mutual information between regions separated by a sharp annular region. Possible extensions to higher dimensions and hyperscaling violating geometries is also considered for disjoint sectors.Comment: 35 pages, 25 Figures, v2: presentation improved, v3: matches published version in JHE

Energy Analysis and Energy Conservation Options for the Addition to Records Storage Building

The energy use and peak load requirements of the addition to Records Storage Building in Austin, Texas were analyzed using the DOE 2.1B building energy simulation program. An analysis was made for the building as specified in schematic designs and primary drawings. To reduce the solar heat gain of the building through the windows and skylights, a glass with high reflectivity and low overall heat transfer coefficient was used to study the reduction of glass conduction and glass solar loads. Other options which were studied included increasing the wall and roof insulation,- reducing the light level, temperature setback, and implementing the proposed ASHRAE standards. Finally, the energy consumption of the building was compared with the energy consumption of the building with solar film and other options which conformed to the proposed ASHRAE energy standard

How to Form the Knowledge that Marketers Need? An Approach for Marketers to SMEs

International audienceTraditionally, the formula for knowledge consists of belief and truth. The key challenge behind this is to understand how a marketer can benefit from this knowledge. Like the traditional Chinese saying, the reason a ship floats or sinks is the same, it is because of water. Similarly, the success or failure of a marketing campaign depends on knowledge. For a marketer, useful knowledge is the combination between the truth and the customer " s belief

Transitional Adaptation model for facilitating technology and expertise mobilisation in Gulf AEC Organisations

The fragmented nature of the Architecture, Engineering, and Construction (AEC) industry is well recognised, the main issues of which relate to failures in communication, process, productivity and interoperability. These failures have contributed to an increased proliferation of adversarial relationships between the different parties involved in projects, the result of which have deleteriously affected projects. Challenges include a range of issues, from the veracity of design information throughout the project lifecycle, through to supply chain communication. These are global issues. For example, in the Gulf States, the nature and complexity of AEC projects has changed significantly due to increased globalisation and the emergence of enmeshed transnational practices. This has created an overwhelming reliance on the mobilisation and transfer of technology/expertise of professional expatriates, which has influenced the approach taken to traditional design and construction business models, including staff roles and procedures. New knowledge and ways of working are needed to support future projects in the Gulf States. There is also a requirement to capture and codify domain-specific expertise. This paper discusses the need to enhance Qatar’s AEC industry by fostering a smooth transition from its current position, into a more sustainable [replicable] state. The philosophical underpinnings of this paper take into account disparate socio-cultural, environmental and economic impacts of change, in terms of business models, technology, innovation, labour market needs, local laws/bylaws, and legislation. A theoretical growth model is presented for discussion. This builds on the experience of the UK (in particular) in terms of facilitating the mobility and penetration of technology/expertise/change in the AEC sectors. This paper presents a series of recommendations needed to develop a Pervasive Transnational Adaptation model for Qatar and the Gulf States, covering such issues as: ICT adoption, agile project management, technology-transfer, innovation, offsite construction, Public Private Partnerships, capacity building, and international strategic alliances

Transformability in post-earthquake houses:towards a more sustainable design approach in Iran

Earthquake is one of the most calamitous disasters in Iran. The hazards of earthquake are always catastrophic not only during the disaster time but also for a long time after the disaster. Since Iran has particular financial and time constraints, hurriedly made post-earthquake emergence shelters often fail in complying with the minimum needs of the occupants. Thereby, such shelters have always been either abandoned or transformed substantially. Since the initial designs are not thoroughly tailored as to address the future's transformational needs, such transformations need comprehensive replacements in terms of structure and construction. Regardless of the other issues that could be brought by these redundant works, they are always associated with an overwhelming waste of resources. In other words, the carbon-footprint of the buildings is often increased significantly only due to not so informed initial decisions by the designers. This study explored the difficulties of the post-disaster housing transformations in Lar city, Iran as a real-life case of study. This paper reports the needs and difficulties of people for transforming their post-earthquake houses. Due to the particular economic and socio-cultural conditions of Iran, the paper proposes to integrate “short-term” and “long-term” housing reconstruction models in order to help the victims have basic but transformable houses immediately after the disaster. In other words, the paper suggests that the potential transformation must be taken into account during very early design and construction stages. The paper contributes to design research and practice and opens new avenues towards more sustainable design with respect to post-earthquake housing projects

Information Theoretical Analysis of Identification based on Active Content Fingerprinting

Content fingerprinting and digital watermarking are techniques that are used for content protection and distribution monitoring. Over the past few years, both techniques have been well studied and their shortcomings understood. Recently, a new content fingerprinting scheme called {\em active content fingerprinting} was introduced to overcome these shortcomings. Active content fingerprinting aims to modify a content to extract robuster fingerprints than the conventional content fingerprinting. Moreover, contrary to digital watermarking, active content fingerprinting does not embed any message independent of contents thus does not face host interference. The main goal of this paper is to analyze fundamental limits of active content fingerprinting in an information theoretical framework.Comment: 35th WIC Symposium on Information Theory in the Benelu

Apparent histological changes of adipocytes after treatment with CL 316,243, a β-3-adrenergic receptor agonist

Background and objectives: The objective of this experiment was to study the effect of CL 316,243 (CL) (a highly selective β3-adrenergic receptor agonist) on cellular changes occurring in retroperitoneal white adipose tissue (RWAT) of lean and obese rats.Methods: Ten-month-old lean and obese Zucker rats were implanted subcutaneously with osmotic mini-pumps, infusing either saline or CL (1 mg/kg body weight/day) for 4 weeks. Results: There was no effect of CL on food intake. However, the resting metabolic rate in lean and obese rats increased by 55 and 96 per rat, respectively. Total RWAT weight decreased in both lean and obese rats under influence of CL treatment by 65 and 38, respectively. Total body weight and body fat were lower in CL treated rats. Detection of uncoupling protein 1 (UCP1) in RWAT was confirmed qualitatively by both immunohistochemistry and immunofluorescence using a rabbit anti rat UCP1 antibody which showed the appearance of a marked increase of this protein in the adipose tissue. Stained semi-thin sections (0.5 µm) also demonstrated abundant nuclei in multilocular adipocytes, in endothelial cells associated with the vasculature, and in interstitial cells. In CL-treated obese rats, a clustering of several multilocular cells around the periphery of a white adipocyte was seen.Conclusion: These results indicate that treatment of both lean and obese Zucker rats with CL induces extensive remodeling of RWAT that includes shrinkage of white adipose tissue, appearance of abundant multilocular cells in RWAT together with the appearance of a marked increase of UCP, preferentially in lean rats. © 2015 Ghorbani et al
