Anti-counterfeiting via federated RFID tags' fingerprints and geometric relationships

RFID has been widely adopted as an effective method for anti-counterfeiting. Legacy systems based on security protocol are either too heavy to be affordable by passive tags or suffering from various protocol-layer attacks, e.g. reverse engineering, cloning, side-channel. In this work, we present a novel anti-counterfeiting system, TagPrint, using COTS RFID tags and readers. Achieving a low-cost and offline genuineness validation utilizing passive tags has been a daunting task. Our system achieves these three goals by leveraging a few of federated tags' fingerprints and geometric relationships. In TagPrint, we exploit a new kind of fingerprint, called phase fingerprint, extracted from the phase value of the backscattered signal, provided by the COTS RFID readers. To further solve the separation challenge, we devise a geometric solution to validate the genuineness. We have implemented a prototype of TagPrint using COTS RFID devices. The system has been tested extensively over 6,000 tags. The results show that our new fingerprint exhibits a good fitness of uniform distribution and the system achieves a surprising Equal Error Rate of 0.1% for anti-counterfeiting.
JMangler - a framework for load-time transformation of Java class files

Current proposals for load-time transformation of Java classes are either dependent on the use of a specific class loader or dependent on a specific JVM implementation. This is not due to an inadequacy of the Java platform but to the wrong choice of the level at which to hook into the Java Class Loader Architecture. JMangler follows a novel approach that ensures both class loader and JVM independence by hooking into the base class of all class loaders. Furthermore, existing proposals do not allow transformers to be treated as components because implicit dependencies must be resolved manually. The paper shows that automatic composition is possible for the well-defined class of interface transformations that still include powerful transformations, like addition of fields, methods and classes, and changes to the class hierarchy. Consequently, interface transformers can be deployed jointly even if developed independently.
Voltage Contrast for Gate-Leak Failures Detected by Electron Beam Inspection

We examine a technique for enhancing the voltage contrast (VC) of a failure analysis (FA) tool, defect review scanning electron microscope (DR-SEM). For an SRAM, we demonstrate a dependence of gate-leak VC on the relative angle (RA) between the direction of beam scanning by the FA tool and the lengthwise direction of the gate electrode. Experimental results show that better VC results are obtained when RA is zero, in other words, a beam's scan-line is parallel with the SRAM gate. We propose a simple qualitative resistor-capacitor model to explain this phenomenon. With the help of this VC enhancement technique of the FA tool, we could tune the electron beam inspection (EBI) recipe to an appropriate condition quicker. The cycle time of EBI recipe tuning was shortened from five to two days. As a result, correct EBI evaluation results of countermeasure experiments led us to a yield enhancement solution within a shorter period of time.
Attempting to predict success in the qualifying round of the International Chemistry Olympiad

The aim of this study was trying to predict success in the qualifying round for the International Chemistry Olympiad (IChO) on the basis of the expectancy-value model of achievement motivation by Eccles et al. The investigation with 52 participants, including 14 females, was conducted during the third of four qualifying rounds of the IChO in Germany. The subjects filled in a questionnaire, took an intelligence test, and participated in two theoretical chemistry exams. Male and female Olympians showed large differences in parental support, motivation, and emotion as well as test performance. Ultimately, only one female participant qualified for the fourth round of the IChO. The model of Eccles et al. was well suited for predicting test performance in the competition. The strongest predictor was found to be the participation in a previous IChO. The implications for reducing gender differences and promoting scientifically talented students are discussed.
Structural cooperativity in histone H3 tail modifications

Post‐translational modifications of histone H3 tails have crucial roles in regulation of cellular processes. There is cross‐regulation between the modifications of K4, K9, and K14 residues. The modifications on these residues drastically promote or inhibit each other. In this work, we studied the structural changes of the histone H3 tail originating from the three most important modifications; tri‐methylation of K4 and K9, and acetylation of K14. We performed extensive molecular dynamics simulations of four types of H3 tails: (i) the unmodified H3 tail having no chemical modification on the residues, (ii) the tri‐methylated lysine 4 and lysine 9 H3 tail (K4me3K9me3), (iii) the tri‐methylated lysine 4 and acetylated lysine 14 H3 tail (K4me3K14ace), and (iv) tri‐methylated lysine 9 and acetylated lysine 14 H3 tail (K9me3K14ace). Here, we report the effects of K4, K9, and K14 modifications on the backbone torsion angles and relate these changes to the recognition and binding of histone modifying enzymes. According to the Ramachandran plot analysis; (i) the dihedral angles of K4 residue are significantly affected by the addition of three methyl groups on this residue regardless of the second modification, (ii) the dihedral angle values of K9 residue are similarly altered majorly by the tri‐methylation of K4 residue, (iii) different combinations of modifications (tri‐methylation of K4 and K9, and acetylation of K14) have different influences on phi and psi values of K14 residue. Finally, we discuss the consequences of these results on the binding modes and specificity of the histone modifying enzymes such as DIM‐5, GCN5, and JMJD2A.
An evaluation of two different exercise regimes during the first year following stroke: A randomised controlled trial

The purpose of this randomised controlled trial was to evaluate the effects of two different exercise approaches during the first 12 months post stroke on Instrumental Activities of Daily Living (IADL), motor function, gait performance, balance, grip strength, and muscle tone. This study is a double-blind longitudinal randomised trial of first-time-ever stroke patients. Seventy-five patients were included: 35 in an intervention group and 40 in a self-initiated exercise group. After discharge from acute rehabilitation, patients assigned in the intervention group had physiotherapy for a minimum amount of 80 hours during the first year. Patients in the self-initiated exercise group were not recommended any specific therapy besides treatment when needed. Main outcome measures were Instrumental Activities of Daily Living according to Fillenbaum, Motor Assessment Scale, 6-Minute Walk Test, Berg Balance Scale, Timed Up-and-Go Test, grip strength, Modified Ashworth Scale, and pulse monitoring. The patients were tested on admission, at discharge, and after 3, 6, and 12 months post stroke by an experienced investigator, blinded to group assignment. Twelve months post stroke showed higher levels of independence in all items of the Instrumental Activities of Daily Living Test and improvements in the results of Motor Assessment Scale, 6-Minute Walk Test, Berg Balance Scale, Timed Up-and-Go, and grip strength in both groups. Only a few significant differences were seen between groups, and they were in favour of the self-initiated exercise group (e.g., ability to use the telephone independently). Attending examination sessions following each intervention phase appeared to be strong motivators for training, irrespective of group allocation.
A risky business: An examination of Irish probation officers’ attitudes towards risk assessment

This article examines recent research on risk assessment and probation practice in Ireland and relates the findings to the ongoing debate regarding risk management practices in probation. The piece discusses current theoretical arguments on the influence of risk in criminal justice and outlines the impact of risk discourse on probation practice in Ireland and England and Wales. Using a mix of qualitative and quantitative methods, Irish probation officers’ attitudes are examined in order to highlight key issues facing probation officers when making risk decisions. These findings are compared and contrasted to other research results from England and Wales. All the conclusions identify both positive and negative consequences of adopting risk tools and point to the continued salience of clinical judgment over actuarial methods of risk assessment. It is argued that the research highlights the role of ‘resistance’ by criminal justice professionals in mediating the effects of the ‘new penology’ at the level of implementation. The idea of resistance holds particular relevance for probation practice in Ireland where professional discretion is maintained within the National Standards framework. Despite this, to date there has been an uncritical approach taken to risk assessment which may ignore the dangers of risk inflation/deflation and the need to take into account local factors in assessing risk of reoffending.
Failure of exchange reamed intramedullary nails for ununited femoral shaft fractures.

OBJECTIVE To determine the effectiveness of exchange reamed nails for treatment of aseptic femoral delayed unions and nonunions. DESIGN Retrospective chart review. PATIENTS Nineteen patients admitted to the Carolinas Medical Center Level I trauma center from 1990 to 1996 for repair of femoral shaft fracture nonunion following contemporary locked nailing performed at least six months previously. These patients showed no radiographic evidence of progression of fracture healing for three months and had clinical symptoms of nonunion. INTERVENTION Exchange reamed nails to treat ununited femoral shaft fracture. MAIN OUTCOME MEASUREMENTS Radiographic and clinical evidence of union of the fracture or of the necessity for additional procedures. RESULTS In 53 percent of the patients the secondary procedure resulted in fracture union, whereas in 47 percent, one or more additional procedures were required. Eight of the nine fractures that did not unite with exchange nailing united after a subsequent procedure (bone grafting, compression plating, or nail dynamization). Neither the type of nonunion, the location of the shaft fracture, the use of static versus dynamic cross-locking, nor the use of tobacco products was statistically predictive of the need for additional procedures. CONCLUSIONS Reevaluation of routine exchange nailing as the recommended treatment for aseptic femoral delayed union or nonunion may be required. A significant number of patients who undergo reamed exchange nailing will require additional procedures to achieve fracture healing.
Carbamates and Benzodiazepines have different effects on detoxified alcoholics' sleep polygraphy

We showed in a previous work that tetrabamate (molecular complex composed of febarbamate, difebarbamate and phenobarbital) induced delta sleep in alcoholics, compared to diazepam. The aim of the present study was to test the hypothesis that the effect of tetrabamate on delta sleep was due to the carbamate part of the drug. We compared the effects of diazepam, tetrabamate, and meprobamate on 32 recently detoxified alcoholic inpatients' sleep polygraphy. Except for sleep duration and wake after sleep onset, tetrabamate and meprobamate groups had a similar polygraphic profile, in contrast to diazepam. Compared to the diazepam group, tetrabamate and meprobamate groups showed a decrease in stage 2 and an increase in stage 4. The effects of tetrabamate and meprobamate on stage 4, compared to diazepam, had comparable amplitudes. We propose the hypothesis that carbamates exert their action on delta sleep through an antagonist effect on 5HT‐2 or histamine H1 receptors.
Globalized Andes? Livelihoods, Landscapes and Development

Contemporary globalization in the Andes challenges the sustainability and quality of rural livelihoods. However, it is also the case that rural people have often addressed these destructive dimensions of economic globalization through a progressively deeper engagement in other types of globalized relationship. They have done this by organizing, through engagements with networks linking them to international actors, and through participation in new product and labor markets. While such global entanglements do not guarantee local development and empowerment, they offer one of the few ways to confront the demise of rural localities. This paper discusses such sets of globalized relationships in four localities in Bolivia, Ecuador and Peru. Particular attention is paid to the ways in which the emergence and activities of local organizations and social movements have been affected by the nature of their relationships with wider transnational development networks, and the constraints and possibilities that come with these relationships. The cases demonstrate how forms of global entanglement vary greatly across sites, and so suggest that the effects of globalization on livelihoods and landscapes are not easy to judge normatively or ex ante. Instead they imply that rather than speaking of globalization generically, it is important to consider the types and sequences of globalized relationships in which people and places have been enmeshed. This suggests the need for historically situated studies of ‘glocalization’ in order to understand both the actual processes of livelihood change under conditions of globalization, and the conditions under which more sustainable and locally governed rural livelihoods and landscapes might be built.
The Share , Coincidence and Dominance Measures for Itemsets : Extended Report

We introduce the measures share, coincidence and dominance as alternatives to the standard itemset methodology measure of support. We also redefine the confidence measure in this context. An itemset is a group of items bought together in a transaction. The support of an itemset is the ratio of transactions in which an itemset appears to the total number of transactions. The share of an itemset specifies the ratio of the count of items purchased together to the total count of items purchased in all transactions. The coincidence of an itemset is the ratio of the count of items in that itemset to the total of those same items in the database. The dominance of an item in an itemset specifies the extent to which that item dominates the total of all items in the itemset. Measures based on share have the advantage of reflecting accurately how many units are being moved by a business, a capability that current itemset methodology does not provide. In addition, the share can be extended to give an accurate picture of the financial impact of an itemset on the business bottom line.

A 17.5 fJ/bit energy-efficient analog SRAM for mixed-signal processing

An energy-efficient analog SRAM (A-SRAM) is proposed to eliminate redundant analog-to-digital (A/D) and digital-to-analog (D/A) conversions in the mixed-signal processing such as a biomedical and a neural network applications. The D/A and the A/D conversion are integrated into the SRAM readout by the charge sharing of the proposed split bit-line (BL) and the SRAM write by the successive approximation method, respectively. And a data structure is newly proposed to allocate each bit of the input data to the binary-weighted bit-cell array. The proposed A-SRAM is implemented using 65 nm CMOS technology. As a result, it achieves 17.5 fJ/bit read energy-efficiency and 21 Gbit/s read throughput, which are 54% lower and 1.3× higher than the conventional SRAM. Also, the area is reduced by 31% compared to the conventional SRAM with ADC and DAC.
Stream Data Mining : A Survey

A data stream is a massive, continuous and rapid sequence of data elements. Mining data streams raises new problems for the data mining community about how to mine continuous high-speed data items that you can only have one look at. Due to this reason, traditional data mining approach is replaced by systems of some special characteristics, such as continuous arrival in multiple, rapid, time-varying, possibly unpredictable and unbounded. Analyzing data streams help in applications like scientific applications, business
The Optimization of Xen-Based Display Virtualization

Virtualization technology can reuse the hardware platform to provide multiple isolated virtual system environments; however, this also causes unsatisfactory performance of the virtual guest system, especially the display in virtual guest system. In this paper, we study the virtual device model and improve the way of original virtual device implement based on Xen virtualization. A new display method is adopted which does improve the display environment of virtual guest system effectively.
Age of initiation with different substances and relationships with resources and vulnerabilities: A cross-national study

There is still limited knowledge about the interrelations among the age of initiation of different substances and the diverse aspects of adolescent functioning. The present cross-national study aimed at exploring the presence of a time-order pattern of age of initiation of different substances and the relationships with personal and relational resources and vulnerabilities, drawn from the problem behaviour theory by Jessor et al. (1991). The sample consisted of 970 adolescents from Italy and The Netherlands, of whom 198 were fully initiated in alcohol, first tobacco use, regular tobacco smoking and marijuana. In both countries, cumulative scale analyses showed the presence of a pattern of age of initiation in the different types of substances. The earlier the age of onset of one substance, the earlier the age of onset of the other substances. Furthermore, the higher the personal resources and the healthy, conventional parents and friend models, the older the age of initiation of different substances by both Dutch and Italian adolescents. With respect to the use of alcohol, the higher the relational resources, the older the age of initiation. Conversely, the higher the adolescents perceived relational vulnerabilities, the younger their age of initiation in drugs. These findings suggest that preventive interventions might be more successful when they are precocious, enhance personal capabilities, and produce changes in the adolescent life context.
History and description of the Anni Bergman Parent-Infant Program

Abstract It is a proud occasion to have papers written by graduates of the Anni Bergman Parent-Infant Training Program published by The International Journal of Infant Observation. Our programme in New York, far younger than the Tavistock Clinic, is beginning its fourteenth year. The papers collected here reflect how the programme has facilitated psychoanalytically informed infant observation and clinical work with mothers, fathers, and infants in a variety of settings. Several years ago, Rita Reiswig, a founding director of the Anni Bergman Parent-Infant Program, contacted Lisa Miller about collaborating on an issue of Infant Observation. Gloria Demby and Susannah Falk Shopsin, graduates of the programme, took on the task of bringing the project to fruition. We are grateful to Beth Miller and the entire editorial board of Infant Observation, headed by Lisa Miller, for a rich collaboration with us over the past months that has culminated in this edition of the journal. The following introduction describes the beginning of our training programme and provides an overview of the ideas that have influenced the programme today – its areas of study, and our beginning expansion into clinical work in community settings and research.
[Correction of forearm deformities in children with multiple cartilaginous osteochondromas].

AIM Deformity of the forearm with shortening and bowing is common in children with multiple cartilaginous osteochondromas. The objective of this study was to evaluate the benefit of ulnar lengthening using an external fixateur in these patients. METHOD 9 patients (10 cases) underwent surgery of the forearm between 1995 and 2001 and were evaluated using a standard protocol. The mean follow-up was 33.6 months, the mean age at operation 8.9 years. All patients were treated with ulnar lengthening, in 6 cases combined with an excision of the osteochondromas. RESULTS Four out of ten patients did show an improvement in postoperative forearm rotation, two deteriorated and 4 presented unchanged. Wrist motion improved in 7 patients and remained unchanged in 3. The postoperative radial articular angle showed an improvement in 6, the carpal slip in 9 of the patients. The preoperative radial head dislocation in one patient remained unchanged postoperatively. CONCLUSION The authors advocate this therapeutic concept for the correction of forearm deformity in multiple hereditary osteochondromas to prevent a progression of the deformity and to establish carpal stability. A significant improvement of forearm and wrist function could not be reached.
Reliable hard real-time communication in industrial and embedded systems

This paper presents a framework for how to use ARQ (automatic repeat request) in combination with real-time worst-case scheduling analysis to be able to support reliable hard real-time communication. We show how to handle retransmissions of erroneous data packets, while still not jeopardizing stated delay guarantees of other packets. We demonstrate this by taking a point-to-point link as an example. Through our simulation studies we have shown that a reduction of the message error rate by several orders of magnitude is possible with a reasonable utilization penalty.
Incremental Recomputation of Active Relational Expressions

Database updates are small and incremental compared to database contents. It is therefore desirable that recomputations of active relational expressions-such as views, derived data, integrity constraints, active queries, and monitors-can also be performed incrementally. An efficient algorithm for the incremental recomputation of active relational expressions based on finite differencing techniques is presented. Database updates are modeled as incremental changes to database relations, and the algorithm derives, by update propagation, the minimal incremental relational expressions that need recomputation. The algorithm has applications in the maintenance of materialized views and derived data, the checking of integrity constraints, and the evaluation of active queries and monitors. >
