An efficient reliable PUF-based cryptographic key generator in 65nm CMOS

Physical unclonable functions (PUFs) are primitives that generate high-entropy, tamper resistant bits for use in secure systems. For applications such as cryptographic key generation, the PUF response bits must be highly reliable, consistent across multiple evaluations under voltage and temperature variations. Conventionally, error correcting codes (ECC) have been used to improve response reliability, but these techniques have significant area, power, and delay overheads and are vulnerable to information leakage. In this work, we present a highly-reliable, PUF-based, cryptographic key generator that uses no ECC, but instead uses built-in self-test to determine which PUF bits are reliable and only uses those bits for key generation. We implemented a prototype of the key generator in a 65nm bulk CMOS testchip. The key generator generates 1213 bits in an area of <;50k/μm2 with a measured bit error rate of <; 5 * 10-9 in both the nominal and worst case corners (100k measurements each). This is equivalent to a 128-bit key failure rate of <; 10-6. The system can generate a 128-bit key in 1. 15μs. Finally, we present a realization of a “strong”-PUF that uses 128 of these highly reliable bits in conjunction with an Advanced Encryption Standard (AES) cryptographic primitive and has a response time of 40ns and is realized in an area of 84k/μm2.
Indications and Contraindications for Liver Transplantation

Patients with chronic liver disease and certain patients with acute liver failure require liver transplantation as a life-saving measure. Liver transplantation has undergone major improvements, with better selection of candidates for transplantation and allocation of scarce deceased donor organs (according to more objective criteria). Living donor liver transplantation came into existence to overcome the shortage of donor organs especially in countries where there was virtually no deceased donor programme. Advances in the technical aspects of the procedure, the intraoperative and postoperative care of both recipients and donors, coupled with the introduction of better immunosuppression protocols, have led to graft and patient survivals of over 90% in most high volume centres. Controversial areas like transplantation in alcoholic liver disease without abstinence, acute alcoholic hepatitis, and retransplantation for recurrent hepatitis C virus infection require continuing discussion.
The Resilient Turn: College Students' Perspectives A Phenomenological Inquiry

This qualitative phenomenology was designed to explore with a sample of undergraduate students in psychology-related majors their perceptions of psychological resilience and the factors they believe contributed to it. While previous studies have examined the construct of resilience in childhood and adolescence, relatively little is known about the phenomenon later in the lifespan. Thus, the rationale for the study stems from the researcher’s wish to fill this gap in knowledge by studying resilience among emerging adults. It was the researcher’s assumption that the knowledge generated from this study would both provide new insights into emerging adult resilience and inform higher education practice. The sample was composed of seven undergraduate students in psychology-related majors who reported a history of trauma as well as a sense of personal thriving. Data was collected primarily through in-depth interviews, and supportive methods of questionnaire and document/artifact review were also utilized. Coding and analysis of data were organized by the research questions, and analysis and interpretation of findings were organized in categories based on the study’s conceptual framework. The study revealed that (a) while there are many aspects of emerging adult resilience, it is characterized primarily by the ability to successfully integrate trauma; (b) taking action steps contributed to resilience by targeting the disconnection and disempowerment that can result from trauma; and (c) resilience often both motivates students to pursue a psychology-related education and is an outcome of their engagement in the curriculum as they heal from their own traumatic experiences. Recommendations are offered for practice and policy in higher education and for future research.
Visual attention inspired distant view and close-up view classification

The images of distant view and close-up view indicate a photographers' attention which can be further utilized for user behavior analysis and scene evaluation. As images may compose arbitrary contexts, distant view and close-up view classification becomes non-trivial. In this work, we found two cues can represent human visual attention, i.e. focus cue and scale cue. We model the focus cue in frequency domain using the Discrete Wavelet Transform, and employ signal distribution as the focus feature. For the scale cue, we model it by defining a spatial size and a conceptual size in the image using the Edge Box and Convolution Neural Network. By integrating these two models, a robust scheme is proposed for this non-trivial task. Experiments on a newly retrieved dataset, which has 2137 natural images, show the classification accuracy achieves up to 97.3%.
Moral Elevation and Moral Beauty: A Review of the Empirical Literature

Moral elevation is defined as the emotional response to witnessing acts of moral beauty. Studies have found that elevation entails pleasant feelings of warmth in the chest, feeling uplifted, moved, and optimistic about humanity. Elevation motivates affiliation with others as well as moral action tendencies. The main goal of this review was to gather and organize the empirical findings from the last 16 years of elevation research with regard to psychological and physiological characteristics, motivational tendencies, behavioral outcomes, neuronal mechanisms, moderators, and correlates of elevation. A secondary goal was to examine whether elevation is congruent with Fredrickson's (2001) broaden-and-build theory of positive emotions. It was concluded that there is strong evidence that elevation broadens the thought-action repertoire and relatively weak evidence that it builds lasting resources. Potential evolutionary functions, the forms of measurement of elevation, the process of how elevation is triggered, practical applications and directions for future research were also addressed.
Association of Simple Anthropometric Indices and Body Fat with Early Atherosclerosis and Lipid Profiles in Chinese Adults

Objective The discriminatory capability of different adiposity indices for atherosclerosis and lipid abnormalities remains uncertain. This study aimed to identify the best adiposity index for predicting early atherosclerosis and abnormal lipid profiles among anthropometric parameters and body fat measures in middle-aged and elderly Chinese. Method A total of 2,063 women and 814 men (57.6±5.2 y) were recruited for this community-based cross-sectional study. Body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were assessed. Body fat mass and its percentage values for the whole body and trunk were measured by bioelectrical impedance analysis (BIA). The intima-media thicknesses (IMTs) of the common carotid arteries (CCA), internal carotid arteries (ICA) and bifurcation (BIF) were determined via B-mode ultrasound. The fasting lipid profiles were assessed. Results With per SD increase of adiposity indices, the magnitude of the changes of IMT values and lipid profiles was more substantial for WC, WHR and WHtR in both genders. A multivariate logistic regression analysis indicated that WC, WHR and WHtR were more sensitive in predicting the presence of intima-media thickening at the three segments as well as the lipids disturbances in women and men. In general, BIA-derived measures have no added predictive value for IMT-thickening as opposed to those three traditional abdominal measures. Conclusion Our findings suggest that abdominal anthropometric measures including WC, WHR and WHtR are sensitive for discriminating carotid atherosclerosis and lipids abnormalities. WC is the best index because of its simplicity in routine use.
Interactive Effects of Warming and Increased Precipitation on Community Structure and Composition in an Annual Forb Dominated Desert Steppe

To better understand how warming, increased precipitation and their interactions influence community structure and composition, a field experiment simulating hydrothermal interactions was conducted at an annual forb dominated desert steppe in northern China over 2 years. Increased precipitation increased species richness while warming significantly decreased species richness, and their effects were additive rather than interactive. Although interannual variations in weather conditions may have a major affect on plant community composition on short term experiments, warming and precipitation treatments affected individual species and functional group composition. Warming caused C4 grasses such as Cleistogenes squarrosa to increase while increased precipitation caused the proportions of non-perennial C3 plants like Artemisia capillaris to decrease and perennial C4 plants to increase.
Improved embryo development in Japanese black cattle by in vitro fertilization using ovum pick-up plus intracytoplasmic sperm injection with dithiothreitol

The purpose of this study was to determine whether dithiothreitol (DTT) treatment of sperm and ethanol activation improve embryo production by intracytoplasmic sperm injection (ICSI). Further, we compared ICSI with standard in vitro fertilization (IVF) in oocytes obtained from cattle. We demonstrated that DTT reduced the disulfide bond in the bovine sperm head. Using oocytes obtained from a slaughterhouse, ICSI-DTT treatment without ethanol showed the highest rate of blastocyst formation. We applied these results to fertilization using ovum pick-up (OPU). Eleven Japanese black cattle served as donors for OPU plus standard IVF (OPU-IVF). Of them, four donors with low embryo development rates were selected to determine whether embryo development was enhanced by OPU plus ICSI (OPU-ICSI). We assessed effects on embryo development following IVF and ICSI in oocytes obtained using OPU. Blastocyst rates were significantly higher for OPU-ICSI than for OPU-IVF. Our results suggest that OPU-ICSI improves the blastocyst development rate in donors with low embryo production compared with the standard OPU-IVF.
Population Structure and Historical Demography of the Oriental River Prawn (Macrobrachium nipponense) in Taiwan

The oriental river prawn (Macrobrachium nipponense) is a non-obligatory amphidromous prawn, and it has a wide distribution covering almost the entire Taiwan. Mitochondrial DNA fragment sequences of the cytochrome oxidase subunit I (COI) and 16S rRNA were combined and used to elucidate the population structure and historical demography of oriental river prawn in Taiwan. A total of 202 individuals from six reservoirs and three estuaries were separately collected. Nucleotide diversity (π) of all populations was 0.01217, with values ranging from 0.00188 (Shihmen Reservoir, SMR, northern Taiwan) to 0.01425 (Mingte Reservoir, MTR, west-central Taiwan). All 76 haplotypes were divided into 2 lineages: lineage A included individuals from all sampling areas except SMR, and lineage B included specimens from all sampling locations except Chengching Lake Reservoir (CLR) and Liyu Lake Reservoir (LLR). All F ST values among nine populations were significantly different except the one between Jhonggang River Estuary (JGE, west-central Taiwan) and Kaoping River Estuary (KPE, southern Taiwan). UPGMA tree of nine populations showed two main groups: the first group included the SMR and Tamsui River Estuary (TSE) (both located northern Taiwan), and the second one included the other seven populations (west-central, southern and eastern Taiwan). Demographic analyses implied a population expansion occurred during the recent history of the species. The dispersal route of this species might be from China to west-central and west-southern Taiwan, and then the part individuals belonging to lineage A and B dispersed southerly and northerly, respectively. And then part individuals in west-central Taiwan fell back to and stay at estuaries as the sea level rose about 18,000 years ago.
CRISPR1 analysis of naturalized surface water and fecal Escherichia coli suggests common origin

Clustered regularly interspaced short palindromic repeats (CRISPRs) are part of an acquired bacterial immune system that functions as a barrier to exogenous genetic elements. Since naturalized Escherichia coli are likely to encounter different genetic elements in aquatic environments compared to enteric strains, we hypothesized that such differences would be reflected within the hypervariable CRISPR alleles of these two populations. Comparison of CRISPR1 alleles from naturalized and fecal phylogroup B1 E. coli strains revealed that the alleles could be categorized into four major distinct groups (designated G6–G9), and all four allele groups were found among naturalized strains and fecal strains. The distribution of CRIPSR G6 and G8 alleles was similar among strains of both ecotypes, while naturalized strains tended to have CRISPR G7 alleles rather than G9 alleles. Since CRISPR G7 alleles were not specific to naturalized strains, they, however, would not be useful as a marker for identifying naturalized strains. Notably, CRISPR alleles from naturalized and fecal strains also had similar spacer repertoires. This indicates a shared history of encounter with mobile genetic elements and suggests that the two populations were derived from common ancestors.
Managing the development of shared service centers: stakeholder considerations

Politicians and public managers continue to debate over whether to centralize or to decentralize departments, information systems and services. Shared service centers (SSCs) are gaining importance in public administration as a means to innovate, to reduce costs and to increase service levels. The discussions about the decision whether to use SSCs seem to be predominantly focused on efficiency and effectiveness aspects, which are rational arguments.In this paper we describe and analyze the introduction of a SSC within a municipality from a stakeholder perspective and centralization/decentralization strategy. Our analysis suggests that that implementation of SSCs should pay careful attention to the management of the implementation process. In our case study we found that most of the stakeholders considered the SSC as a complete centralization strategy in the initiating stage. During the implementation stage of the SSC they became aware that it would not be a completely centralized; a mixed decentralization/ centralization strategy was taken. An active stakeholder management strategy can help to set the right expectations, creating a sense of urgency and avoid misconceptions.
Arboreal Ant Colonies as ‘Hot-Points’ of Cryptic Diversity for Myrmecophiles: The Weaver Ant Camponotus sp. aff. textor and Its Interaction Network with Its Associates

Introduction Systematic surveys of macrofaunal diversity within ant colonies are lacking, particularly for ants nesting in microhabitats that are difficult to sample. Species associated with ants are generally small and rarely collected organisms, which makes them more likely to be unnoticed. We assumed that this tendency is greater for arthropod communities in microhabitats with low accessibility, such as those found in the nests of arboreal ants that may constitute a source of cryptic biodiversity. Materials and Methods We investigated the invertebrate diversity associated with an undescribed, but already threatened, Neotropical Camponotus weaver ant. As most of the common sampling methods used in studies of ant diversity are not suited for evaluating myrmecophile diversity within ant nests, we evaluated the macrofauna within ant nests through exhaustive colony sampling of three nests and examination of more than 80,000 individuals. Results We identified invertebrates from three classes belonging to 18 taxa, some of which were new to science, and recorded the first instance of the co-occurrence of two brood parasitoid wasp families attacking the same ant host colony. This diversity of ant associates corresponded to a highly complex interaction network. Agonistic interactions prevailed, but the prevalence of myrmecophiles was remarkably low. Conclusions Our data support the hypothesis of the evolution of low virulence in a variety of symbionts associated with large insect societies. Because most myrmecophiles found in this work are rare, strictly specific, and exhibit highly specialized biology, the risk of extinction for these hitherto unknown invertebrates and their natural enemies is high. The cryptic, far unappreciated diversity within arboreal ant nests in areas at high risk of habitat loss qualifies these nests as ‘hot-points’ of biodiversity that urgently require special attention as a component of conservation and management programs.
Higher-order logical inference with compositional semantics

We present a higher-order inference system based on a formal compositional semantics and the wide-coverage CCG parser. We develop an improved method to bridge between the parser and semantic composition. The system is evaluated on the FraCaS test suite. In contrast to the widely held view that higher-order logic is unsuitable for efficient logical inferences, the results show that a system based on a reasonably-sized semantic lexicon and a manageable number of non-first-order axioms enables efficient logical inferences, including those concerned with generalized quantifiers and intensional operators, and outperforms the state-of-the-art firstorder inference system.
Intranasal Administration of Lentiviral miR-135a Regulates Mast Cell and Allergen-Induced Inflammation by Targeting GATA-3

Mast cell (MC) degranulation is the foundation of the acute phase of allergic rhinitis (AR). Previously, downregulation of GATA binding protein 3 (GATA-3) was shown to suppress MC activation in an AR mouse model. Binding of microRNA-135a (miR-135a) to GATA-3 was also observed, and overexpression of this miRNA decreased GATA-3 mRNA and protein expression. However, the effects of miR-135a on MCs during AR are currently unknown. In the present study, we utilized a lentiviral (LV) vector to intranasally administer miR-135a to ovalbumin (OVA)-sensitized AR mice. Following miR-135a treatment, the total serum IgE concentration observed during AR was significantly reduced. In the nasal mucosa, the expression of T-box expressed in T cells (T-bet) was higher, whereas that of GATA-3 was lower in the AR mice following miRNA treatment. Notably, during AR, the ratio of type 1 T-helper cells (Th1) to type 2 (Th2) cells in the spleen is unbalanced, favoring Th2. However, administering miR-135a to the AR mice appeared to balance this ratio by increasing and decreasing the percentage of Th1 and Th2 cells, respectively. MiR-135a also appeared to strongly suppress the infiltration of eosinophils and MCs into the nasal mucosa, and it was specifically localized in the MCs, suggesting that its influence is modulated through regulation of GATA-3 in these cells. Additional work identifying the full therapeutic potential of miR-135a in the treatment of AR and diseases involving allergen-induced inflammation is warranted.
Online Distance Measurement for Tree Data Event Streams

Distances for trees have already been researched for decades. Thus most of the research is focused on static tree data. E.g. the calculation of XML documents when considering the aggregation of different data sources. Nowadays rising amounts of data require analysis on data streams. This results in the analysis of dynamic trees. Analysis on data streams require one-pass algorithms as well as efficient resource utilisation regarding memory and CPU. Our use case is the network traffic monitoring and analysis of batch jobs in a batch system. The monitoring data is delivered via a monitoring event stream per batch job. Each batch job implements specific workflows that build up the dynamic tree structure. To compare the batch jobs efficiently against each other over time, we utilise an incremental distance measurement for dynamic trees. This paper presents the incremental distance measurement. It utilises a sketching of trees using signatures. Furthermore we rely on hash tables to realise fast access and calculations. We analyse the properties of our incremental distance measurement and compare it to the well-known tree edit distance. All experiments are performed on real world data and confirm the feasibility and scalability of our approach.
Comparison of Academic Achievement Between Montessori and Traditional Education Programs

Abstract The purpose of this study was to compare the academic achievement of 543 urban 4th- (n=291) and 8th- (n=252) grade students who attended Montessori or traditional education programs. The majority of the sample consisted of minority students (approximately 53 percent), and was considered low income (approximately 67 percent). Students who attended a public Montessori school were compared with students who attended structured magnet, open magnet, and traditional non-magnet public schools on standardized measures of math and language arts. Results of the study failed to support the hypothesis that enrollment in a Montessori school was associated with higher academic achievement. Implications and suggestions for future research are provided.
Understanding the appeal of user-generated media: a uses and gratification perspective

Purpose – User‐generated media (UGM) like YouTube, MySpace, and Wikipedia have become tremendously popular over the last few years. The purpose of this paper is to present an analytical framework for explaining the appeal of UGM.Design/methodology/approach – This paper is mainly theoretical due to a relative lack of empirical evidence.
