How does the Library Searcher Behave? A Contrastive Study of Library Search against Ad-hoc Search

We investigated the search behaviour of the library searcher using the log data from The European Library (TEL). We were especially interested in how this behaviour compares to the search behaviour of ad-hoc searchers, represented by log data in the MSN search engine. At first sight, the two data sets mainly differ in the topics of the queries entered and their multi-lingual vs. mono-lingual content. When studying user behaviour, session information is very important: how does the user navigate through the engine’s interface? We visualized the TEL users’ interactions with the system by creating a transition network for the users’ intra-session actions. In general, we think that research into user behaviour on the basis of search engine logs can be very informative for the evaluation of search engine interfaces.

Reference Input/Output Medium Metric RGB Color Encoding (RIMM/ROMM RGB)

A new color encoding specification known as Reference Output Medium Metric RGB (ROMM RGB) is defined. This color encoding is intended to be used for storing, interchanging and manipulating images that exist in a rendered image state without imposing the gamut limitations normally associated with device-specific color spaces. ROMM RGB was designed to provide a large enough color gamut to encompass most common output devices, while simultaneously satisfying a number of other important criteria. It is defined in a way that is tightly linked to the ICC profile connection space (PCS) and is suitable for use as an Adobe Photoshop™ working color space. A companion color encoding specification, known as Reference Input Medium Metric RGB (RIMM RGB), is also defined. This encoding can be used to represent images in an unrendered scene image state.
Lecture 24: Iterative Closest Point and Earth Mover's Distance

The ICP algorithm seeks to minimize the RMSD, by alternating between a matching step and a transformation step. In the matching step, given a certain rotation and translation, the optimal matching is calculated by minimizing the RMSD. In the transformation step, given a matching, the optimal rotation and translation are computed. This alternating process terminates when the matching remains unchanged in sucessive iterations. The following is an algorithmic description of ICP: ICP(A,B)
The effect of Etomidate on sensory transmission in the dorsal column pathway in the urethane‐anaesthetized rat

The effect of Etomidate, a general anaesthetic, on sensory afferent transmission was measured in the dorsal column pathway in urethane‐anaesthetized rats. Extracellular recordings were made of peripherally evoked responses by single cells in the cuneate nucleus, ventroposterolateral nucleus of the thalamus and laminae IV–VI of the primary somatosensory cortex. Cortical mass responses were also recorded. In further experiments, cortical mass responses were evoked antidromically by stimulation in the pyramidal tract. The effect of incremental administration of Etomidate on evoked responses was recorded. These results are compared with the previously reported effects of urethane, a ‘conventional’ anaesthetic. Etomidate did not alter cuneate or ventroposterolateral thalamic cell responses but it caused a dose‐dependent reduction in cortical cell responsiveness. It failed to alter antidromically evoked cortical mass responses. Etomidate differs from the majority of anaesthetics, which act in the thalamus, and appears to cause perturbation at the cortical level.
Protein Trafficking to the Apicoplast: Deciphering the Apicomplexan Solution to Secondary Endosymbiosis

Almost 20 years ago, the first sequence was published from a 35-kb circular molecule found in Plasmodium falciparum , the most virulent of human malaria parasites ([20][1]). Consistent with the expected mitochondrial origin of the small genome, the sequence showed strong similarities to eubacterial
Dynamic nets-to-TSVs assignment in 3D floorplanning

We propose a new scheme of dynamic nets-to-TSVs assignment during floorplanning for 3D-ICs. A nontrivial area occupied by TSVs, their physical dimensions, location on the layout and the nets-to-TSVs assignment, are some of the key factors influencing the wirelength, TSV count and chip area, and consequently, impact the total delay. We address the above issues by simultaneous placement of TSV islands with circuit blocks, assignment of nets to TSV islands during floorplanning and directly optimizing interconnect delay. TSVs induce significant thermo-mechanical stress in nearby silicon, and to reduce the impact of stress, we incorporate pitch and Keep-Out-Zone (KOZ) around TSVs in our approach. The proposed dynamic nets-to-TSVs assignment approach, improves solution compared to a previously used fixed nets-to-TSVs assignment, by achieving on average 6-9% delay reduction. Analysis for various TSV aspect ratios using the proposed assignment method is also presented.
POSTER: Implementing and Testing a Novel Chaotic Cryptosystem for Use in Small Satellites

Cryptography in the domain of small satellites is a relatively new area of research. Compared to typical desktop computers, small satellites have limited bandwidth, processing power, and battery power. Many of the current encryption schemes were developed for desktop computers and servers, and as such may be unsuitable for small satellites. In addition, most cryptographic research in the domain of small satellites focuses on hardware solutions, which can be problematic given the limited space requirements of small satellites. This paper investigates potential software solutions that could be used to encrypt and decrypt data on small satellites and other devices with similarly limited resources. Specifically, this paper presents an implementation of an encryption algorithm based on chaos theory and compares and contrasts it with existing cryptographic schemes used in desktop computing and lightweight applications.
Does Particularism Solve the Moral Problem?

Abstract Moral cognitivism, internalism about moral judgements, and Humeanism about motivating reasons all possess attractions.Yet they cannot all be true.This is the so–called moral problem. Dancy offers an interesting particularist response to the moral problem. However, we argue that this response, first, provides an inadequate basis for the distinction between motivating states and states necessary for motivation although not themselves motivators; second, draws no support from considerations about weakness of the will; and third, involves an implausible account of desire.We conclude that particularism ú whatever other attractions it may have ú does not solve the moral problem. 1We would like to thank Jonathan Dancy, Paul Robinson, and two anonymous referees for very helpful comments on earlier drafts of this paper.
Compact dual-band microstrip band pass filter design based on stub loaded resonator for wireless applications

A simple, compact design of dual-band bandpass filter is introduced in this paper. The proposed filter is based on stub loaded resonator (SLR). It is composed of two stub loaded half wavelength open ring resonators. The design is performed in two steps to obtain the required dual-band response. The first band is produced by using two half wave open ring resonators while the other band is obtained by loading a stub to the half wave open ring resonator. The resulting bands are at 2.4 GHz and 4.3 GHz. The two bands are independent and can be tuned by varying the dimensions of the open ring and the stub respectively. The modeled filter was designed using Rogers TMM10 substrate with relative dielectric constant of 9.2 and thickness of 0.635 mm. The dimensions of the designed filter are found to be about 0. 3λg × 0. 32λg. Simulated results show that the proposed filter offered good transmission and reflection responses as well as high out of band rejection. Measured results are found to be in reasonable agreement with those predicted by the simulation. The parametric study performed for the designed filter shows that the dual band resonant behavior has a significant ratio of the resonant bands. This feature yields an adequate filter to be used for many wireless communication applications.
On the Resonant Behavior Analysis of Small-Size Slot Antenna with Different Substrates

An analysis of resonant behavior of small-size slot antenna with substrates of different electrical permittivity has been presented in this paper. It has been observed that with increase in electrical permittivity of the substrate, the gain of the antenna increases, while there is decrease in bandwidth and input impedance of the antenna. Also there is shift of resonant frequency toward lower side with this increase in substrate’s dielectric constant. Results shows that the proposed antenna may be used as small, compact antenna for X-band applications General Terms Substrates, Resonant behavior.
Emergent gamma synchrony in all-to-all interneuronal networks

We investigate the emergence of in-phase synchronization in a heterogeneous network of coupled inhibitory interneurons in the presence of spike timing dependent plasticity (STDP). Using a simple network of two mutually coupled interneurons (2-MCI), we first study the effects of STDP on in-phase synchronization. We demonstrate that, with STDP, the 2-MCI network can evolve to either a state of stable 1:1 in-phase synchronization or exhibit multiple regimes of higher order synchronization states. We show that the emergence of synchronization induces a structural asymmetry in the 2-MCI network such that the synapses onto the high frequency firing neurons are potentiated, while those onto the low frequency firing neurons are de-potentiated, resulting in the directed flow of information from low frequency firing neurons to high frequency firing neurons. Finally, we demonstrate that the principal findings from our analysis of the 2-MCI network contribute to the emergence of robust synchronization in the Wang-Buzsaki network (Wang and Buzsáki, 1996) of all-to-all coupled inhibitory interneurons (100-MCI) for a significantly larger range of heterogeneity in the intrinsic firing rate of the neurons in the network. We conclude that STDP of inhibitory synapses provide a viable mechanism for robust neural synchronization.
Formal Characterization of Illegal Control Flow in Android System

The dynamic taint analysis mechanism is used to protect sensitive data in the Android system. But this technique does not detect control flows which can cause an under-tainting problem. This means that some values should be marked as tainted, but are not. The under-tainting problem can be the cause of a failure to detect a leak of sensitive information. To solve this problem, we use a set of formally defined rules that describes the taint propagation. We prove the completeness of these rules. Also, we provide a correct and complete algorithm based on these rules to solve the under-tainting problem.
Evaluation of analgesics and anti-inflammatory activity of a poly-herbal formulation.

Rheumatoid arthritis is a chronic multi-systemic disease of unknown cause. It affects the people in their prime of life, predominantly between the ages of 20-50 years with unpredictable course. Various poly-herbal formulations are used in the ayurvedic system of medicine for the treatment of inflammation and pain associated with rheumatoid arthritis, osteo-arthritis, frozen shoulder, ankylosing spondylitis and chronic backache. Our study was aimed to evaluate efficacy of poly-herbal formulation using different animal models such as hot plate reaction time, acetic acid induce writhing in mice, carrageen (1% v/v)-induced paw edema and formaldehyde-induced paw edema. The results indicated that the poly-herbal formulation possesses good analgesic and anti-inflammatory activities in the experimental animal models.
Feature Transfer and Matching in Disparate Stereo Views through the Use of Plane Homographies

Many vision tasks rely upon the identification of sets of corresponding features among different images. This paper presents a method that, given some corresponding features in two stereo images, matches them with features extracted from a second stereo pair captured from a distant viewpoint. The proposed method is based on the assumption that the viewed scene contains two planar surfaces and exploits geometric constraints that are imposed by the existence of these planes to first transfer and then match image features between the two stereo pairs. The resulting scheme handles point and line features in a unified manner and is capable of successfully matching features extracted from stereo pairs that are acquired from considerably different viewpoints. Experimental results are presented, which demonstrate that the performance of the proposed method compares favorably to that of epipolar and tensor-based approaches.
Pyrrolidine Dithiocarbamate Prevents Neuroinflammation and Cognitive Dysfunction after Endotoxemia in Rats

Systemic inflammation, for example as a result of infection, often contributes to long-term complications. Neuroinflammation and cognitive decline are key hallmarks of several neurological conditions, including advance age. The contribution of systemic inflammation to the central nervous system (CNS) remains not fully understood. Using a model of peripheral endotoxemia with lipopolysaccharide (LPS) we investigated the role of nuclear factor-κB (NF-κB) activity in mediating long-term neuroinflammation and cognitive dysfunction in aged rats. Herein we describe the anti-inflammatory effects of pyrrolidine dithiocarbamate (PDTC), a selective NF-κB inhibitor, in modulating systemic cytokines including tumor necrosis factor (TNF)-α and interleukin-1β (IL-1β) and CNS markers after LPS exposure in aged rats. In the hippocampus, PDTC not only reduced neuroinflammation by modulating canonical NF-κB activity but also affected IL-1β expression in astrocytes. Parallel effects were observed on behavior and postsynaptic density-95 (PSD95), a marker of synaptic function. Taken together these changes improved acute and long-term cognitive function in aged rats after LPS exposure.
Regulation of hematopoietic cell function by inhibitory immunoglobulin G receptors and their inositol lipid phosphatase effectors

Summary: Numerous autoimmune and inflammatory disorders stem from the dysregulation of hematopoietic cell activation. The activity of inositol lipid and protein tyrosine phosphatases, and the receptors that recruit them, is critical for prevention of these disorders. Balanced signaling by inhibitory and activating receptors is now recognized to be an important factor in tuning cell function and inflammatory potential. In this review, we provide an overview of current knowledge of membrane proximal events in signaling by inhibitory/regulatory receptors focusing on structural and functional characteristics of receptors and their effectors Src homology 2 (SH2) domain‐containing tyrosine phosphatase 1 and SH2 domain‐containing inositol 5‐phosphatase‐1. We review use of new strategies to identify novel regulatory receptors and effectors. Finally, we discuss complementary actions of paired inhibitory and activating receptors, using FcγRIIA and FcγRIIB regulation human basophil activation as a prototype.
Diversification in news recommendation for privacy concerned users

With more and more news sources publishing news articles online, news recommendation systems are becoming increasingly popular in recent days. However, if a news recommender shows to the user many news articles that cover same story or talk about same persons or events, then the recommendations might become monotonous for the user. A possible way to handle this scenario is to diversify the recommended news articles so that the articles in the recommendation list are not too similar to each other. Existing research works in literature discuss how to use user-specific relevance of news articles and diversification to produce the final recommendations. To be able to compute user-specific relevance of articles, several recommender systems suggest that users have a login, or they set cookies to track page visits of the users. Often users are unsure whether the information collected via these means will be used for the sole purpose of news recommendation. Privacy of the identity and page access patterns is a concern for many users. In this work, we consider the problem where diverse recommendations are to be given for users, but no past data about users is collected or stored by the system. We use only article popularity to estimate the relevance. We identify few aspects of news articles on which diversification can be performed. These aspects are incorporated in an optimization framework. An approximation algorithm is used to generate the recommendations. Experimental analysis shows that in scenarios where no individual user data is stored or accessible by the recommender system, diversification results in higher click rates and increase in the number of satisfied users. Performances of the multiple diversification aspects and approaches are also analyzed.
A fuzzy multicriteria decision‐making methodology for selection of human resources in a Greek private bank

Purpose – The purpose of this paper is to present a fuzzy multicriteria decision‐making (MCDM) methodology for selecting employees.Design/methodology/approach – The methodology is based on the technique for order preference by similarity to ideal solution (TOPSIS) multicriteria decision tool and the algorithm presented by Karsak. Assuming that n are candidates each of whom is evaluated in j criteria, the methodology starts by defining the ideal and the anti‐ideal candidate.Findings – The applicability of the methodology is discussed using real data from a major Greek bank. As a result, it is necessary to consider criteria, criteria weights, and the distances from both the ideal and the anti‐ideal solution in order to select the more appropriate candidate.Research limitations/implications – Modern approaches recognize that selection of human resources is a complex process that involves a significant amount of vagueness and subjectivity, and serious consideration for candidate's uncertainties of career life.
Texture extraction from photographs and rendering with dynamic texture mapping

There is a natural trend in modeling a scene on a computer with minimum effort of the user. Wireframe modeling and texturing is the main two factors that affect the quality of results in computer graphics. In this paper, instead of 3D model reconstruction, automatic texture extraction and texture registering for surfaces are discussed. Deficiency of the artificial textures to create photorealistic results leads to us using real textures for rendering. Assuming that camera parameters, lighting conditions, 3D model and its surface properties are known and the image sequences of the scene are provided by the user, textures for surfaces can be extracted from images. Naturally, textures coming from different images need to be enhanced. Some artifacts, i.e., highlights, distortion from perspective projection should be removed. Unlike traditional texture mapping which generates a single texture for a surface, multiple textures are used in rendering. A selection mechanism enables us to choose the best texture from multiple textures according to the orientation of the viewpoint. The texture, which is mapped, is not unique and static. Therefore, it is called dynamic texture mapping. Experiments show that the results are promising.
Stimulation of Osteogenesis in Bone Defects Implanted with Biodegradable Hydroxyapatite Composed of Rod-Shaped Particles under Mechanical Unloading

The aim of this study was to evaluate the influence of mechanical unloading on the repair of bone defects with implantation of biodegradable bone substitutes. Spherical granules of biodegradable hydroxyapatite composed of rod-shaped particles (RHA) or beta-tricalcium phosphate composed of rod-shaped particles (RTCP) were implanted into a bone defect created in the distal end of the right femur of 8-week-old Wistar rats. Two, 6, 10, and 22 weeks after implantation, part of the sciatic nerve in the thigh was resected and exposed to mechanical unloading for 2 weeks. Then, 4, 8, 12 and 24 weeks after implantation, repair of the bone defect was analyzed. As a control, the bone defect without implantation of ceramic granules was also analyzed. Both RHA and RTCP tended to be reduced, but the reduction was not obvious during the experimental period. At 12 and 24 weeks after implantation, the amount of newly formed bone in the animal implanted with RHA was significantly greater than that at 4 weeks after implantation, but that in the animal implanted with RTCP or without implantation was not significantly different. The number of osteoclasts in the region implanted with RHA was significantly larger than that of the region implanted with RTCP or without implantation at 12 and 24 weeks. The activities of alkaline phosphatase in osteoblasts and tartrate-resistant acid phosphatase in osteoclasts were remarkably increased in the bone defects with implantation compared with those in the bone defects without implantation. These results suggested that RHA stimulated osteogenesis and osteoclastogenesis even after 2 weeks of mechanical unloading, and that RHA could be expected to improve the repair of bone defects in patients under the condition of skeletal unloading.
Postdoctoral researchers: roles, functions and career prospects

Concerns with postdoctoral research training and employment outcomes are growing at an international level. Recent studies of postdoctoral and other contract researchers in various countries emphasize common issues associated with these appointments, including the absence of any systematic definition of postdoctoral research positions, lack of policy and data on postdoctoral researchers, and increasing dissatisfaction among postdoctoral researchers with the nature of their position and with their future employment prospects. These issues are explored further in the study reported here, through an interview‐based investigation of the views of both postdoctoral researchers and postdoctoral supervisors with regard to the nature of postdoctoral research positions and the career development support provided within those positions. Key findings include substantial variation in the functions of postdoctoral researchers, and in the perceived purposes of such positions. Despite a widespread perception among both p.
