On the Power of Public-key Functional Encryption with Function Privacy

In the public-key setting, known constructions of function-private functional encryption (FPFE) were limited to very restricted classes of functionalities like inner-product [Agrawal et al. PKC 2015]. Moreover, its power has not been well investigated. In this paper, we construct FPFE for general functions and explore its powerful applications (both for general functions and for specific efficient instantiations). As warmup, we construct from FPFE a natural generalization of a signature scheme endowed with functional properties, that we call functional anonymous signature (FAS) scheme. In a FAS, Alice can sign a circuit C chosen from some distribution D to get a signature σ and can publish a verification key that allows anybody holding a message m to verify that (1) σ is a valid signature of Alice for some (possibly unknown to him) circuit C and (2) C(m) = 1. Beyond unforgeability the security of FAS guarantees that the signature σ hide as much information as possible about C except what can be inferred from knowledge of D. Then, we show that FPFE can be used to construct in a black-box way functional encryption schemes for randomized functionalities (RFE). Previous constructions of (public-key) RFE relied on iO [Goyal et al. TCC 2015]. As further application, we show that efficient instantiations of FPFE can be used to achieve adaptivelysecure CNF/DNF encryption for bounded degree formulae (BoolEnc). Though it was known how to implement BoolEnc from inner-product encryption [Katz et al. EUROCRYPT 2008], as already observed by Katz et al. this reduction only works for selective security and completely breaks down for adaptive security. For this application we only need weak assumptions and the resulting adaptivelysecure BoolEnc scheme is efficient. Finally, we present a general picture of the relations among all these related primitives. One key observation is that Attribute-based Encryption with function privacy implies FE, a notable fact that sheds light on the importance of the function privacy property for FE.
Toward a Process Model of IT Adoption Ambidexterity: A Revelatory Case-Study

Central to a process of IT adoption is the managerial ability to simultaneously balance the continuous exploring of the technology and its advantages, while also exploiting it. It is this simultaneity that we refer to as IT adoption ambidexterity, and recognize as an area in need of research. Based on prior research on organizational ambidexterity, this study employed a case study to investigate IT adoption at RE/MAX LLC, a global real estate franchise. The question guiding the investigation was: how were the exploration and exploitation activities that contributed to the firm’s IT adoption balanced over time? The study yielded qualitative data to propose a process model of IT adoption ambidexterity, highlighting the capabilities that contribute to ambidexterity at each phase of the adoption. Implications of this model for research and practice are discussed and propositions for future research are offered.
Interpretation of Chinese Address Information Based on Multi-factor Inference

Interpretation of Chinese address information, which refers to translating the non-specification Chinese address into the concrete administration divisions, is a critical prerequisite in Internet geography semantic comprehension and Chinese address navigation. In this paper, We proposed Multi-factor(MF) Inference technology to solve the problem of vague address semantics. Firstly, we define the location and match factors of each geographical element in a series of address, which need to be included in a various address relationship. Secondly, the reliability of each possible address string is inferred. Finally, the highest reliability is choosed. Expriments show that our method outperforms current state-of-the-art methds.
A Hierarchic Architecture for Conceptual Information

Conceptual retrieval returns information related to a speciic topic but not restricted to a query term. A common approach is to compare the query with all the documents in the database. When the number of documents is large, the searching time becomes signiicant. In this paper, we propose a hierarchic architecture which integrates latent semantic indexing (LSI) and hierarchic agglomerative clustering to reduce the searching time. We employ three clustering algorithms (single link, complete link, and group average) and conduct experiments on four standard document collections (CACM, CISI, CRAN, and MED). The experimental results show our method requires less searching time while maintaining comparable retrieval eeectiveness as non-clustered search.
Supporting Service Differentiation and Maximizing System Saturation Throughput: A Contradictory in IEEE 802.11e WLAN

While most existing work focuses separately on how to improve WLAN saturation throughout and how to provide differentiated service, few attention is put to study their relationship. In this paper, we investigate the impact of service differentiation on saturation throughput maximization in IEEE 802.11e WLANs and theoretically prove that it is contradictory and impossible to achieve both of them simultaneously. In other words, saturation throughput is maximized without service differentiation or service differentiation reduces the maximal achievable saturation throughput more or less.

Power Allocation for Full-Duplex Relay Selection in Underlay Cognitive Radio Networks: Coherent versus Non-Coherent Scenarios

This paper investigates power control and relay selection in Full Duplex Cognitive Relay Networks (FDCRNs), where the secondary-user (SU) relays can simultaneously receive data from the SU source and forward them to the SU destination. We study both non-coherent and coherent scenarios. In the non-coherent case, the SU relay forwards the signal from the SU source without regulating the phase; while in the coherent scenario, the SU relay regulates the phase when forwarding the signal to minimize the interference at the primary-user (PU) receiver. We consider the problem of maximizing the transmission rate from the SU source to the SU destination subject to the interference constraint at the PU receiver and power constraints at both the SU source and SU relay. We then develop a mathematical model to analyze the data rate performance of the FDCRN considering the self-interference effects at the FD relay. We develop low-complexity and high-performance joint power control and relay selection algorithms. Extensive numerical results are presented to illustrate the impacts of power level parameters and the self-interference cancellation quality on the rate performance. Moreover, we demonstrate the significant gain of phase regulation at the SU relay.
Where is Helvellyn? Fuzziness of multi‐scale landscape morphometry

The landscape in which people live is made up of many features, which are named and have importance for cultural reasons. Promient among these are the naming of upland features such as mountains, but mountains are an enigmatic phenomenon which do not bear precise and repeatable definition. They have a vague spatial extent, and recent research has modelled such classes as spatial fuzzy sets. We take a specifically multiresolution approach to the definition of the fuzzy set membership of morphometric classes of landscape. We explore this idea with respect to the identification of culturally recognized landscape features of the English Lake District. Discussion focuses on peaks and passes, and the results show that the landscape elements identified in the analysis correspond to well-known landmarks included in a place name database for the area, although many more are found in the analysis than are named in the available database. Further analysis shows that a richer interrogation of the landscape can be achieved with Geographical Information Systems when using this method than using standard approaches. © Royal Geographical Society (with The Institute of British Geographers) 2004.
UvA-DARE (Digital Academic Repository) Elephants and optimality again: SA-OT accounts for pronoun resolution in child language

Children display a surprising delay in correctly resolving pronouns, while they employ Chomsky’s binding principles correctly in production and in resolving reflexives. We account for the mistakes as performance errors that are predicted by an Optimality Theoretical model implemented using simulated annealing. Our experiments suggest three novel explanations of the facts. Additionally, the Optimality Theory–Harmony Grammar connection is also explored: the behaviour of the HG-based performance model converges to the OTmodel if the base of the exponential weights grow large.
On the role of Glu‐68 in alcohol dehydrogenase

Theoretical computations (molecular dynamics and combined quantum chemical and molecular mechanical geometry optimizations) have been performed on horse liver alcohol dehydrogenase. The results provide evidence that Glu‐68, a highly conserved residue located 0.47 nm from the catalytic zinc ion, may intermittently coordinate to the zinc ion. Structures with Glu‐68 coordinated to the zinc ion are almost as stable as structures with Glu‐68 at the crystal position and the barrier between the two configurations of Glu‐68 is so low that it can readily be bypassed at room temperature. There is a cavity behind the zinc ion that seems to be tailored to allow such coordination of Glu‐68 to the zinc ion. It is suggested that Glu‐68 may facilitate the exchange of ligands in the substrate site by coordinating to the zinc ion when the old ligand dissociates.
Resilience pathways, childhood escape routes, and mentors reported by gay and bisexual men affected by syndemic conditions

Investigation of the social and psychological antecedents of the HIV epidemic has identified a syndemic of conditions associated with risk behavior and seroconversion. This study inquires into the resilient practices and developmental processes of gay and bisexual men at the nexus of syndemic conditions to understand the pathways that lead to health problems or well-being. Interviews with 40 men identified branching pathways from home environments into schools that either offer refuge or a regime of gender discipline and bullying. Some found escape routes from hostile environments in worlds of books, pop culture, or internet chat. In adolescence, one set of men identified the development of sexual relationships with older men as a lifeline that brought a measure of emotional growth. This study points to resilience pathways and social resources that could make a difference in the lives of those deemed to be “high risk. ”
Understanding IT Business Value Creation and Evaluation in Least Developed Economies

Information Technology (IT) is an important resource that can facilitate growth and development in both the developed and developing economies. The forces of globalisation increase the digital divide between the developed and developing economies is increasing. The least developed economies (LDEs) are the most vulnerable within this environment. Intense competition for IT resources means that LDEs need a deeper understanding of how to source and evaluate their IT‐related efforts. This effort puts LDEs in a better position to source funding from various stakeholders and promote localized investment in IT. This study presents a complementary approach to securing better IT‐related business value in organizations in the LDEs. It further evaluates how IT and the complementaries need to managed within the LDEs. Analysis of data collected from five LDEs show that organizations that invest in IT and related complementaries are able to better their business processes. The data also suggest that improved business processes lead to overall business processes improvements. The above is only possible if organizations adopt IT and make related changes in the complementary resources within the established culture and localizing the required changes.
T-cell regulatory gene CTLA-4 polymorphism/haplotype association with autoimmune pancreatitis.

BACKGROUND Autoimmune pancreatitis (AIP) is a distinct disease entity of chronic pancreatitis. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is a key negative regulator of the T-cell immune response, and its gene is highly polymorphic. Many positive associations between cytotoxic T-lymphocyte-associated protein 4 (CTLA4) single-nucleotide polymorphisms and various autoimmune diseases have been identified. We investigated possible genetic associations of CTLA4 in a Chinese population with AIP. METHODS We performed genotyping for CTLA4 (49 A/G, -318 C/T, and CT60 A/G) and tumor necrosis factor (TNF)-alpha promoter (-857 C/T, -863 C/A, and -1031 C/T) by use of PCR sequence-specific primers and direct sequencing, respectively, in 46 patients with AIP, 78 patients with chronic calcifying pancreatitis (CCP), and 200 healthy individuals. RESULTS We found a significant increase in CTLA4 49A carriers in patients with AIP compared with healthy individuals (78.3% vs 48%; P <0.0001). The frequency of CTLA4 49A was also significantly higher in patients with AIP compared with CCP (78.3% vs 37.1%; P <0.0001). CTLA4 49A conferred a higher risk of AIP [with CCP, odds ratio (OR) 7.20; P <0.0001]. The -318C/+49A/CT60G haplotype was associated with a higher susceptibility to AIP (OR 8.53; P = 0.001). The TNF-alpha promoter -863A was associated with extrapancreatic involvement in patients with AIP. CONCLUSION CTLA-4 49A polymorphism and -318C/+49A/CT60G haplotype are associated with AIP in a Chinese population.
Increasing flexibility and capacity in real PON deployments by using 2/4/8-PAM formats

Current passive optical networks (PONs) use on–off keying (OOK) modulation throughout the entire network regardless of actual path losses. Statistics of commercial gigabit passive optical network (GPON) deployments show significant path loss differences among the optical network units (ONUs). Flexible 4- and 8-level pulse amplitude modulation (4/8-PAM) allocation for the better-situated ONUs can significantly increase the PON’s aggregated data rate. By keeping to intensity modulation direct detection (IM-DD) modulation and a constant symbol rate, the introduction of adaptive, multilevel PAM does not require expensive optics investments; additionally, 8-PAM is made feasible with zero-overhead data-aided equalization. Two scenarios for distributing the extra capacity are explored: first, controlling the dynamic bandwidth allocation of the time division multiplexed PON (TDM-PON) to provide equal time-length slots to both 4/8-PAM ONUs and OOK ONUs, thereby providing maximum aggregated capacity increase; and second, setting up the dynamic bandwidth allocation to provide equal capacity slots to the various ONUs so the entire ONU population in the same PON can benefit from the extra capacity. Both scenarios result in a larger aggregated capacity of the PON and provide additional options for the network operator during the network design phase.
A D-band transceiver front-end for broadband applications in a 0.35μm SiGe bipolar technology

This paper presents a D-band transceiver front-end with twin quadrature receivers fabricated in a low cost 0. 35μm SiGe bipolar production technology, featuring HBTs with fT/fmax of 200/250 GHz. The receiver achieves a minimum single-sideband noise figure of 14 dB, conversion gain greater than 23 dB and an input-referred 1-dB compression point of -9 dBm, at an IF of 10 MHz for input signals between 121-126 GHz. A three stage LO buffer amplifier in the receiver allows operation with LO power as low as -10 dBm. The measured amplitude and phase imbalance at 122 GHz are 1 dB and 6 deg respectively. The transmitter can be tuned from 112 GHz to 140 GHz and delivers a maximum output power of -2.5 dBm. The measured phase noise at 1 MHz offset is -102 dBc/Hz at 140 GHz. The maximum suppression of the V-band signal at the transmitter output is better than -25 dBc. The chip consumes 300 mA from a 3.3 V power supply.
A Context-Aware Resource Management Framework for Smart Homes

There are many devices embedded in a smart home environment. It is a challenge to operate these devices due to the heterogeneity and the mobility of them. In this paper, we propose a context-aware resource management framework, which aims to (1) discover available resources and update the states of those devices according to the changes of contexts; (2) allocate suitable resources to meet the needs of user tasks. Context-awareness facilitates decision making in the process of resource allocation by considering device states and user contexts including user situations, user tasks, device capabilities, and so on. A prototype system is implemented based on the context-aware resource management framework. The prototype system shows that the framework proposed is feasible.
Purification of a membrane-associated protein complex required for protein translocation across the endoplasmic reticulum.

The capacity of microsomal membranes to translocate nascent presecretory proteins across their lipid bilayer can be largely abolished by extracting them with high ionic strength buffers. It can be reconstituted by adding the salt extract back to the depleted membranes [Warren, G. & Doberstein, B. (1978) Nature (London) 273, 569-571]. Utilizing hydrophobic chromatography, we purified to homogeneity a protein component of the salt extract that reconstitutes the translocation activity of the extracted membranes. This component behaves as a homogeneous species upon gel filtration, ion-exchange chromatography, adsorption chromatography, and sucrose-gradient centrifugation. When examined by polyacrylamide gel electrophoresis in NaDodSO4, six polypeptides with apparent Mr of 72,000, 68,000, 54,000, 19,000, 14,000, and 9000 are observed in about equal and constant stoichiometry, suggesting that they are subunits of a complex. The sedimentation coefficient of 11S is in good agreement with the sum of the Mr of the subunits. The Mr 68,000 and 9000 subunits label intensely with N-[3H]ethylmaleimide. Thus, the reported sulfhydryl group requirement of the translocation activity in the unfractionated extract [Jackson, R. C. , Walter, P. & Blobel, G. (1980) Nature (London), 286, 174-176] may be localized to either or both the Mr 68,000 and 9000 subunits of the purified complex.
It Outsourcing At The Stage Of Psychological Contract: Governance-In-Practice And Governance-In-Contract

The governance of IT outsourcing (ITO) has been identified as an essential determinant for ITO success. While prior studies have shed light on how to determine effective governance to inform practice, little research attention has been reversely initiated from practice when certain governance model is implemented. In this paper, I have addressed two concepts of Governance-in-Contract (GiC) and Governance-in-Practice (GiP) incorporating social network perspective and practice theory. The theoretical framework is built upon the stage of psychological contract in Miranda and Kavan’s (2005) Moment of Governance (MoG) model. I applied a portion of the framework in a single case study combining Social Network Analysis (SNA) and document analysis. The findings contrast GiP with GiC, and show how they are interrelated on the same stage of psychological contract. I hope to inspire future studies to further investigate the GiP with qualitative enquiries such as in-depth interviews, combining deeper SNA with pertinent quantitative measures.
Unusually High Archaeal Diversity in a Crystallizer Pond, Pomorie Salterns, Bulgaria, Revealed by Phylogenetic Analysis

Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of presented taxa in hypersaline environment. Archaeal clones were grouped in 26 different operational taxonomic units (OTUs) assigned to 15 different genera from two orders, Halobacteriales and Haloferacales. All retrieved sequences were related to culturable halophiles or unculturable clones from saline (mostly hypersaline) niches. New sequences represented 53.9% of archaeal OTUs. Some of them formed separate branches with 90% similarity to the closest neighbor. Present results significantly differed from the previous investigations in regard to the number of presented genera, the domination of some genera not reported before in such extreme niche, and the identification of previously undiscovered 16S rRNA sequences.
**title** Asp Conference Series, Vol. **volume***, **year of Publication** **names of Editors** Can Quantum Theory Explain Dark Matter?

Certain solutions to a gravitational form of Schrodinger's equation can yield stable, macroscopic eigenstate solutions having no classical analogue, with properties resembling those of dark matter. Some more tractable solutions show: (1) radiative lifetimes far exceeding the universe's age, implying negligible emission and inherent stability w.r. t. gravitational collapse, (2) negligible interaction with EMR and visible matter, (3) potential to give rise to flat rotation curves and (4) eigenstate energies and 'sizes' consistent with that expected for the galactic halo. Traditional baryonic particles occupying such eigenstates will be invisible and weakly interacting, and may be assimilated into galactic evolution scenarios without significantly disturbing BBN ratios. It is proposed that such structures may explain the nature and origin of dark matter.
Requirement of the spindle pole body for targeting and/or tethering proteins to the inner nuclear membrane

Appropriate targeting of inner nuclear membrane (INM) proteins is important for nuclear function and architecture. To gain new insights into the mechanism(s) for targeting and/or tethering peripherally associated proteins to the INM, we screened a collection of temperature sensitive S. cerevisiae yeast mutants for defects in INM location of the peripheral protein, Trm1-II-GFP. We uncovered numerous genes encoding components of the Spindle Pole Body (SPB), the yeast centrosome. SPB alterations affect the localization of both an integral (Heh2) and a peripheral INM protein (Trm1-II-GFP), but not a nucleoplasmic protein (Pus1). In wild-type cells Trm1-II-GFP is evenly distributed around the INM, but in SPB mutants, Trm1-II-GFP mislocalizes as a spot(s) near ER-nucleus junctions, perhaps its initial contact site with the nuclear envelope. Employing live cell imaging over time in a microfluidic perfusion system to study protein dynamics, we show that both Trm1-II-GFP INM targeting and maintenance depend upon the SPB. We propose a novel targeting and/or tethering model for a peripherally associated INM protein that combines mechanisms of both integral and soluble nuclear proteins, and describe a role of the SPB in nuclear envelope dynamics that affects this process.
