Improving MOSFETs’ TID Tolerance Through Diamond Layout Style

This letter describes an experimental comparative study of the total ionizing dose (TID) effects due to Co-60 gamma irradiation between hexagonal (Diamond) and conventional rectangular gates metal-oxide semiconductor field-effect transistors (MOSFETs), regarding the same bias conditions during irradiation. The transistors were manufactured by using the 350 nm commercial bulk complementary metal-oxide semiconductor (CMOS) integrated-circuits (ICs) technology. The innovative hexagonal gate layout proposal can reduce the parameter deviations of TID effects in MOSFETs in, approximately, 30%, 400%, and 100% in terms of the threshold voltage, leakage drain current, and subthreshold slope, respectively, regarding the standard MOSFET counterparts. Therefore, the Diamond MOSFET can be considered as a low-cost alternative device to be used in space CMOS ICs applications.
Towards reinforcement learning for holonic multi-agent systems

Holonic multi-agent system HMAS offers a promising approach to model complex systems. HMAS is based on self-similar entities defined in a holarchical organization. Although some models and frameworks have been proposed for holonic systems, there is no general reinforcement learning method that can be easily implemented in HMAS. This paper presents a reinforcement learning method for HMAS. The holons in different levels have direct effect on learning process of each other through communication. For hierarchical communications between holons, abstract data flows are defined that are used for state estimation, action selection and reward calculation. The proposed learning method includes a self-similar structure in which the learning processes of the holons are independent of their actual positions in the holarchy. A real-world application is also used to show that how the holons can be implemented in practice. Experimental results show that the proposed holonic reinforcement learning method improves the performance.
Exploration objective de l'audition à partir des auditory steady-state responses et adaptation à l'implant cochléaire

Parmi les differentes methodes de mesure objective de l'audition, les Auditory steady-state responses (ASSR) sont en plein developpement et presentent de multiples avantages. Associees a l'implant cochleaire, cette methode permet d'envisager une evaluation des performances de l'implant et une aide precieuse a son reglage. Dans une premiere partie nous avons cherche a evaluer les performances et capacites de la mesure ASSR chez le sujet non implante, au travers de 4 etudes. Nous avons confirme que cette methode permettait une evaluation precise des seuils auditifs. De plus, l'amplitude de cette reponse donne des informations sur la sonie du sujet (Hearing Research) et met en evidence le phenomene de recrutement. Pour finir, en faisant varier l'un des parametres de la stimulation nous pouvons etudier l'impact de la stimulation binaurale. Ces etudes positionnent la mesure ASSR dans un cadre tres large d'evaluation objective de l'audition. Dans une deuxieme partie, nous avons etudie la possibilite de realiser cette mesure ASSR chez le sujet implante cochleaire en validant l'origine de la reponse mesuree et en mettant au point un systeme de mesure. Pour cela nous avons evalue la reponse mesuree chez un groupe de sujets implantes et deduit de la non linearite de la reponse obtenue son origine non artefactuelle (International Journal of Audiology). Cet artefact rencontre lors de la mesure, nous a amenes a modeliser et analyser le signal emis par l'implant, afin d'en extraire les proprietes utiles a la mesure ASSR. Enfin a l'aide du systeme de mesure ASSR ainsi developpe, nous avons mis en evidence la validite de la mesure ASSR chez l'implante cochleaire.
Patterns of Thinking in Militant Extremism

Recurrent features of the thinking pattern (or mind-set) of violent militant extremists are delineated, discussed, and related to previous research and theory. We examined extremist groups from a diverse range of continents, cultures, and political and religious orientations. We compared statements by (and, to some degree, statements about) these groups and formulated 16 themes common to the militant-extremist mind-set. Among these themes are perceptions of a crisis involving violations of posited sacred values, along with justifications for the use of violence to remediate such problems. There are indications that such themes are not infrequent in the general population. For example, research participants failed to strongly disassociate themselves from the sentiments and framings found in the fanatical items, which undercuts the notion that militant-extremist thinking represents bizarre ideation. Militant-extremist thinking appears to represent a major, aggressive form of fanaticism affected by both dispositional and situational factors. Key themes in this thinking pattern might fit together to construct a potentially compelling narrative, which may be a key part of the ideological appeal of salient militant-extremist groups.
Representation Learning and Pairwise Ranking for Implicit and Explicit Feedback in Recommendation Systems

In this paper, we propose a novel ranking approach for collaborative filtering based on Neural-Networks that jointly learns a new representation of users and items in an embedded space as well as the preference relation of users over pairs of items. The learning objective is based on two ranking losses that control the ability of the model to respect the ordering over the items induced from the users preferences, as well as, the capacity of the dot-product defined in the learned embedded space to produce the ordering. The proposed model is by nature suitable for both implicit and explicit feedback and involves the estimation of only very few parameters. Through extensive experiments on several real-world benchmarks, both explicit and implicit, we show the interest of learning the preference and the embedding simultaneously when compared to learning those separately. We also demonstrate that our approach is very competitive with the best state-of-the-art collaborative filtering techniques proposed independently for explicit and implicit feedback.
Integration of clamped-clamped suspended single-walled carbon nanotubes into SOI MEMS

Processes aiming at integrating suspended single-walled carbon nanotubes (SWNTs) into Micro-Electromechanical Systems (MEMS) have to deal explicitly with the fragility of SWNTs. In general, SWNT growth is delayed to the last step of a process so as to avoid any contamination and physical damage, which restricts the flexibility of an integration process. Here, we present a novel integration process involving a sacrificial bridge structure that provides SWNTs with physical support throughout the process. Thus, post-growth wet processes are enabled, and mechanical rupturing is prevented. With this novel approach, clamped-clamped suspended SWNTs with resistances down to 115 kΩ (with 2 µm suspended segment) are integrated into SOI micro-structures.
A Polygraphic , Polyalphabetic Cryptosystem with Public Key and Private Key Encryption

Cryptosystems may be classified as either public key or private key. The system developed in this paper combines the protocols of these two types of cryptography. Techniques and characteristics of previously established cryptosystems are employed as well to produce a three-pass system that is more secure than these earlier systems. Each transmission in the correspondence protocol is at least triply encrypted. The system is also both polygraphic and polyalphabetic in nature. Furthermore, a digital signature enhances the system security by enabling the recipient of an encrypted message to authenticate the identity of the sender. Finally, a greater computational efficiency is achieved than exists in similar previously established systems due to recent results in number theory.
Interaction between antioxidant vitamin supplementation and cigarette smoking during radiation therapy in relation to long‐term effects on recurrence and mortality: A randomized trial among head and neck cancer patients

There has been concern that the efficacy of radiation therapy may be reduced when patients smoke or take antioxidant vitamins during treatment. Cancer prevention trials with beta carotene supplements documented adverse effects only among smokers. We conducted a randomized trial with alpha tocopherol (400 IU/day) and beta carotene (30 mg/day) supplements among 540 head and neck cancer (HNC) patients treated by radiation therapy. We examined whether smoking during radiation therapy modified the effects of the supplementation on HNC recurrence and on mortality. During the follow‐up, 119 patients had a HNC recurrence and 179 died. Cox models were used to test the interaction between smoking and supplementation and to estimate the hazard ratios (HR) for HNC recurrence and death associated with the supplementation. Cigarette smoking either before or after radiation therapy did not modify the effects of the supplementation. In contrast, the interactions between supplementation and cigarette smoking during radiation therapy were statistically significant for HNC recurrence (p = 0.03), all‐cause mortality (p = 0.02) and mortality from the initial HNC (p = 0.04). Among cigarette smokers, the HR were 2.41 (95% CI: 1.25–4.64) for recurrence, 2.26 (95% CI: 1.29–3.97) for all‐cause mortality and 3.38 (95% CI: 1.11–10.34) for HNC mortality. All corresponding HR among nonsmokers were close to 1. These results could best be explained by the hypothesis that the combined exposures reduced the efficacy of radiation therapy. Particular attention should be devoted to prevent patients from both smoking and taking antioxidant supplements during radiation therapy. © 2007 Wiley‐Liss, Inc.
Capital Investment Appraisal Practices in the Emerging Market Economy of Sri Lanka

Manuscript type: Research paper Research aims: This study aims to investigate the prevalent choice of capital investment appraisal practices and the influence of firm characteristics on the choice of these practices. Design/Methodology/Approach: A survey is conducted by using a sample of 186 Chief Financial Officers (CFOs) from companies listed on the Colombo Stock Exchange platform in Sri Lanka. Research findings: This study reveals that the most popular capital investment appraisal techniques used in Sri Lanka encompass Net Present Value (NPV), followed by Internal Rate of Return (IRR), Payback (PB), Accounting Rate of Return (ARR) and Discounted Payback (DPB). As for the capital investment appraisal tools incorporating risks, Sri Lankan firms prefer uncertainty absorption in cash flows, followed by sensitivity analysis, probability analysis, scenario analysis, and adjusting the required returns. Emerging real options are used at the embryonic stage in Sri Lanka. The use of naive capital budgeting practices is mostly preferred by small firms managed mainly by CFOs with non-MBA educational qualifications with short tenures in the firms. In contrast, sophisticated and advanced capital budgeting practices are mostly used by large firms managed by MBA qualified CFOs with a long tenure in the firms. As for industry differences, ARR is primarily applied by non-MBA CFOs in most non-manufacturing firms. None of the other methods trigger any significant difference in terms of industry types. Theoretical contributions/Originality: This study makes contextual contributions by providing evidence of the application of capital investment appraisal practices in an emerging market economy, namely Sri Lanka. This study also provides parametric contributions as it identifies the influence of firm characteristics on the choice of capital budgeting practices. Practitioner/Policy implications: This study raises the awareness of top management, policy makers, practitioners and stakeholders of companies with regards to capital investment appraisal practices and the influence of firm characteristics on these practices. Research limitations/Implications: A more detailed study encompassing other countries with a similar culture like Sri Lanka is beneficial for further validation, replication and generalisation. Future studies may also consider looking at the influence of behavioral factors in making capital budgeting choices.

The limitations of adaptive dynamics as a model of evolution

Adaptive dynamics describes the evolution of an asexual population through the successive substitution of mutations of small effect. Waxman & Gavrilets (2005) give an excellent overview of the method and its applications. In this note, we focus on the plausibility of the key assumption that mutations have small effects, and the consequences of relaxing that assumption. We argue that: (i) successful mutations often have large effects; (ii) such mutations generate a qualitatively different evolutionary pattern, which is inherently stochastic; and (iii) in models of competition for a continuous resource, selection becomes very weak once several phenotypes are established. This makes the effects of introducing new mutations unpredictable using the methods of adaptive dynamics. We should make clear at the outset that our criticism is of methods that rely on local analysis of fitness gradients (eqn 2 of Waxman & Gavrilets, 2004), and not of the broader idea that evolution can be understood by examining the invasion of successive mutations. We use the term ‘adaptive dynamics’ to refer to the former technique, and contrast it with a more general population genetic analysis of probabilities of invasion.

Also, there will be a short description on the direction of development of the relevant technologies.
Cree leukoencephalopathy and CACH/VWM disease are allelic at the EIF2B5 locus

Cree leukoencephalopathy is a rapidly fatal infantile autosomal recessive leukodystrophy of unknown cause observed in the native North American Cree and Chippewayan indigenous population. We found in the brain of affected individuals the typical foamy cells with the oligodendroglial phenotype described in central hypomyelination syndrome/vanishing white matter, a syndrome related to mutations in the genes encoding the five subunits of the eucaryotic translation initiation factor eIF2B. In three patients of two Cree families, we found a homozygous missense mutation resulting in a histidine substitution at arginine 195 of ε‐eIF2B.
TMAP: Trip Recommendation System Accommodating the Mobile Tourist Preferences

Having or making a trip is a very important component of everyday life. With the new technology, the trip recommendation accommodating the mobile tourist preferences possible and has become a new research area. This type of trip recommendation means planning the most appropriate trip route between locations, based on users' preferences. The purpose of this study brings a new solution to trip recommending for travellers to or residents of a place. For this manner, we examined other mobile applications to expose shortcomings and open features and services to be developed. Tmap is a location based application which enables tourists or any local users with a facility to explore and get information about nearby must see places according to his/her personal point of interest. In the application, the main categories are listed as shopping, architecture/parks, museums, natural places, food/drink/fun and historical places. The places were gathered together in each category according to necessities or interests of the user. The optimized route and direction which the applications displays to the user through an interface which was designed in order to fulfill user’s requirements and demands in the best possible way.
A FAST AND EFFICIENT ISOMORPHIC TASK ALLOCATION SCHEME FOR KARY NCUBE SYSTEMS

A good task allocation algorithm should find available processors for incoming jobs, if they exist, with minimum overhead. Due to its topological generality and flexibility the k-ary n-cube architecture has been chosen for the task allocation problem. We propose a fast and efficient isomorphic processor allocation scheme for k-ary n-cube systems by using isomorphic partitioning where the processor space is partitioned into higher dimensional isomorphic subcube and by using Subcube recognition ability algorithm (SRA) which uses simple coordinate calculation and spatial subtraction. Thus the proposed scheme seeks to reduce the search space drastically, and hence can locate a free subcube very quickly providing scalable, faster, processor allocation, complete recognition ability with minimal overhead and minimizes the fragmentation
Interactions inter-couches et liens à long délai

La demande accrue de services en temps rel, comme la video streaming, justifie le besoin d'etudes qui visent a optimiser le delai de transmission de donnees. En plus du delai de transmission au niveau physique, les delais necessaires a l'acces a la ressource et a la recuperation de donnees venant des couches basses peuvent avoir un impact important sur les performances et ne doivent pas etre negliges. Aussi, des etudes cross-layer doivent etre menees pour minimiser le delai de transmission de l'information. Comprendre l'impact des mecanismes des couches basses sur les performances de bout-en-bout permet un meilleur dimensionnement du reseau, une adaptation du trafic transmis, ou l'introduction de service a faible priorite. Dans cette these, nous avons mesure l'impact des mecanismes des couches liaison et reseau sur les performances de divers protocols de congestion de la couche transport.Dans le contexte des liens 4G par satellite, nous proposons un ensemble d'outils, Trace Manager Tool (TMT) et Cross Layer InFormation Tool (CLIFT), pour simuler de maniere realiste l'ensemble de la couche OSI dans le simulateur de reseau NS-2. Nous avons montre que, pour l'ensemble des variantes de TCP considerees, quand le debit au niveau transport est proche de la capacite de canal, utiliser ARQ au niveau liaison est optimal. Dans le cas ou le taux d'erreur au niveau de la couche physique est plus eleve, H-ARQ permet d'obtenir un meilleur debit au niveau transport.Les dernieres specifications concernant l'acces au lien satellite DVB-RCS2 presentent deux methodes d'acces (aleatoire et dedie) qui peuvent etre implementees pour permettre aux utilisateurs des services proposes par DVB d'aller sur Internet ou de transmettre des donnees. Nous avons developpe un module pour NS-2, Physical Channel Access (PCA), qui modele l'acces au canal pour chacune de ces methodes afin de comparer leur impact sur les performances de bout-en-bout. Nous avons mesure que les methodes d'acces dedie permettent un debit plus important et les methodes d'acces aleatoire une transmission rapide des flots courts. Nous avons donc propose de mixer ces methodes d'acces, en fonction de l'evolution dynamique de la charge du reseau et de la taille du flot de donnees transmis.Finalement, nous avons etudie s'il etait possible d'exploiter les donnees de la gateway du satellite pour introduire un trafic a priorite basse. Nous avons montre qu'il etait possible avec Low Ewtra Delay Background Transport (LEDBAT) comme protocole de la couche transport d'introduire un trafic en tâche de fond. Cependant, en fonction de la variation de la charge du reseau, parametrer correctement des parametres internes a ce protocole sont necessaires.
Structural Correlates of an Anticarcinoma Antibody: Identification of Specificity-Determining Residues (SDRs) and Development of a Minimally Immunogenic Antibody Variant by Retention of SDRs Only

Clinical utility of murine mAbs is limited because many elicit Abs to murine Ig constant and variable regions in patients. An Ab humanized by the current procedure of grafting all the complementarity determining regions (CDRs) of a murine Ab onto the human Ab frameworks is likely to be less immunogenic, except that its murine CDRs could still evoke an anti-variable region response. Previous studies with anticarcinoma mAb CC49 showed that light chain LCDR1 and LCDR2 of humanized CC49 could be replaced with the corresponding CDRs of a human Ab with minimal loss of Ag-binding activity. The studies reported in this paper were undertaken to dissect the CC49 Ag-binding site to identify 1) specificity determining residues (SDRs), the residues of the hypervariable region that are most critical in Ag-Ab interaction, and 2) those residues that contribute to the idiotopes that are potential targets of patients’ immune responses. A panel of variants generated by genetic manipulation of the murine CC49 hypervariable regions were evaluated for their relative Ag-binding affinity and reactivity to sera from several patients who had been immunized with murine CC49. One variant, designated HuCC49V10, retained only the SDRs of CC49 and does not react with the anti-variable region Abs of the sera from the murine CC49-treated patients. These studies thus demonstrate that the genetic manipulation of Ab variable regions can be accomplished by grafting only the SDRs of a xenogeneic Ab onto human Ab frameworks. This approach may reduce the immunogenicity of Abs to a minimum.
Field Trial of 100-km Reach Symmetric-Rate 10G-EPON System Using Automatic Level Controlled Burst-Mode SOAs

This paper reports the world's first field trial of a 100-km reach symmetric-rate ten gigabit Ethernet passive optical network (10G-EPON) system that uses optical-amplifier-based PON repeaters. Semiconductor optical amplifiers (SOAs) are utilized to handle the 10G-EPON wavelength allocation defined in IEEE802.3av; a fast automatic level control technique is applied to cascaded SOAs for upstream amplification to achieve high gain and wide input dynamic range. An electronic dispersion compensation technique is also applied for downstream detection. These techniques support a 79.5-dB loss budget and 100-km reach transmission with 40 km span lengths. In a field trial, we successfully demonstrate bidirectional real-time uncompressed high-definition television signal transmission over installed standard single-mode fiber links.
