Evaluating nature-based solutions for climate mitigation and conservation requires comprehensive carbon accounting
ارزیابی راه حل های مبتنی بر طبیعت برای کاهش و حفاظت از آب و هوا نیاز به حسابداری کربن جامع دارد-2021 Nature-based solutions (NbS) can address climate change, biodiversity loss, human well-being and their
interactions in an integrated way. A major barrier to achieving this is the lack of comprehensiveness in
current carbon accounting which has focused on flows rather than stocks of carbon and led to perverse
outcomes. We propose a new comprehensive approach to carbon accounting based on the whole carbon
cycle, covering both stocks and flows, and linking changes due to human activities with responses in the
biosphere and atmosphere. We identify enhancements to accounting, namely; inclusion of all carbon
reservoirs, changes in their condition and stability, disaggregated flows, and coverage of all land areas.
This comprehensive approach recognises that both carbon stocks (as storage) and carbon flows (as
sequestration) contribute to the ecosystem service of global climate regulation. In contrast, current ecosystem services measurement and accounting commonly use only carbon sequestration measured as net
flows, while greenhouse gas inventories use flows from sources to sinks. This flow-based accounting has
incentivised planting and maintaining young forests with high carbon uptake rates, resulting, perversely,
in failing to reveal the greater mitigation benefit from protecting larger, more stable and resilient carbon
stocks in natural forests. We demonstrate the benefits of carbon storage and sequestration for climate
mitigation, in theory as ecosystem services within an ecosystem accounting framework, and in practice
using field data that reveals differences in results between accounting for stocks or flows. Our proposed
holistic and comprehensive carbon accounting makes transparent the benefits, trade-offs and shortcomings of NbS actions for climate mitigation and sustainability outcomes. Adopting this approach
is imperative for revision of ecosystem accounting systems under the System of EnvironmentalEconomic Accounting and contributing to evidence-based decision-making for international conventions
on climate (UNFCCC), biodiversity (CBD) and sustainability (SDGs).

On addressing RFID/NFC-based relay attacks: An overview
در مورد آدرس دهی حملات رله مبتنی بر RFID / NFC: یک مرور کلی-2019 Relay attacks generally occur between two entities that communicate with each other through wireless means.
When a relay attack between a honest prover and a honest verifier occurs, an adversary tricks the prover and
verifier into believing that they are indeed communicating with each other. Such attacks are rather difficult to
identify and prevent since a passive adversary does not modify any of the communicated messages between
prover and verifier. RFID/NFC-based applications are particularly vulnerable to such attacks. We provide an
overview of RFID-based relay attacks and evaluate various streams of research that have attempted to address
these attacks. Specifically, we consider distance-bounding techniques and the use of artificial or natural ambient
conditions, with specific emphasis on the latter. Keywords: RFID | Relay attack | Cryptography | Ambient conditions |

SlimDna – An in-house expert system for STR profiling
SlimDna - سیستم خبره خانه برای پروفایل سازی STR-2019 At NFC the internally developed software for DNA analysis, SlimDna is used. It is complementary to the LIMS
and keeps track of samples, sample batches, instrument files and generated data. The system communicates with
the LIMS, instruments and other software. SlimDna includes four modules (Analysis, Control, Administration and
Frequency calculation) and covers the entire analysis process from DNA extraction to reporting approved STR
profiles to the LIMS. SlimDna is built with Microsoft Internet Information Services (IIS) as application server and
the user interface consists of Windows clients. For data storage MySQL is used. The software has been implemented
in different packages, STR typing being the latest. The system has streamlined the STR typing by
providing, among other functions, automated evaluation of STR profiles, databases for observed variant alleles
as well as tracking and logging of negative and positive controls. STR electropherograms from analysis of crime
scene samples (around 30 000 per year) are evaluated by SlimDna according to set rules concerning for example
stutter ratio, heterozygote balance and number of alleles per marker in order to define the profile as a single
source genotype or a mixture. The SlimDna output is compared to a manual evaluation before the results are
reported to the LIMS. This process saves nearly one minute hands-on time per sample compared to the previous
Excel-based solution. For reference samples, SlimDna evaluates the majority (55%) of the samples without
manual revision. SlimDna’s automated interpretation has proven to be very accurate and will soon replace more
of the manual revisions. In the near future, we aim to develop SlimDna further, with for example a mixture
module supporting the reporting officers in analysis. Keywords: DNA analysis | Expert system | LIMS |

Decision making guidelines for mining historic landfill sites in Flanders
دستورالعمل های تصمیم گیری برای دفن زباله های معدنی تاریخی فلاندرز-2018 This study aims at showing how the United Nations Framework Classification for Resources (UNFC) can
help to classify potential landfill mining projects with different levels of maturity, from exploration to
production, under technical, socio-economic and project-planning aspects. Taking the example of three
former landfill sites in Flanders general decision making guidelines regarding the future management
of old landfills are provided. Using the ECLAR methodology for the evaluation (E) and classification
(CL) of anthropogenic resources (AR), the individual projects, where clean land and/or materials are
recovered, are mapped under the three-dimensional UNFC system. The Bornem project, yields a negative
Net Present Value (NPV) of 17 Mio € (44 €/t of excavated waste), i.e. the project is currently not eco
nomically viable. In case of changing key parameters the landfill has, however, reasonable prospects for
future economic extraction. The Turnhout land development turned out to be economically viable with a
NPV of 361,000 € (8 €/t of excavated waste). The Zuienkerke remediation project is at a too early stage to
determine its socioeconomic viability. The main focus to compare and prioritize potential landfill mining
projects in Flanders should be on (1) site specific conditions (e.g. landfill’s composition, land prices), (2)
project related factors (e.g. remediation required vs. resource/land recovery, selected technologies and
project set-ups, private vs. public evaluation perspective) and (3) the timing of mining, considering future
development of costs, prices, laws, available data and information.

Optimal Task Allocation in Near-Far Computing Enhanced C-RAN for Wireless Big Data Processing
تخصیص وظیفه بهینه در C-RAN پیشرفته محاسبات نزدیک- دور برای پردازش داده های بزرگ بی سیم-2018 With the increasing popularity of user equipments, the corresponding UE generated big data (UGBD) is also growing substantially, which makes both UEs and current network structures struggle to process those data and applications. This article proposes a near-far computing enhanced C-RAN (NFC-RAN) architecture that can better process big data and its corresponding applications. NFC-RAN is composed of near edge computing (NEC) and far edge computing (FEC) units. NEC is located in the remote radio head,, which can quickly respond to delay-sensitive tasks from the UEs, while FEC sits next to a baseband unit pool, which can do other computation-intensive tasks. Task allocation between NEC and FEC is introduced in this article. Also, WiFi indoor positioning is illustrated as a case study of the proposed architecture. Moreover, simulation and experiment results are provided to show the effectiveness of the proposed task allocation and architecture.

Secured miniaturized system-in-package contactless and passive authentication devices featuring NFC
سیستم امن مینیاتوری در بسته بدون تماس و احراز هویت دستگاه های غیر فعال دارای NFC-2017 RFID/NFC technology is widely spread nowadays and applications can be found in our everyday life, for
example, in payment, transportation, logistics, healthcare, and access control. State-of-the-art contactless
and passive authentication solutions implement relatively large coils outside of the chip. Therefore, the
minimum size is in the order of a few square centimeters, which limits their use for tagging of certain
small-sized goods. On top of that, those miniaturized solutions which are available today provide only
limited security measures.
Here we introduce miniaturized system-in-package contactless authentication devices. This novel solution
integrates Infineon Technologies’ CIPURSETMmove IC, which is a state-of-the-art security solution featur
ing an open security standard, into embedded Wafer Level Ball Grid Array (eWLB) packages, together
with HF-antennas, ferrites, as well as discrete elements that improve HF-coupling characteristics.
The presented devices provide better HF-coupling characteristics than Coil-on-Chip approaches, which
also enable verification of authenticity of tagged products through NFC-enabled smart phones. Thanks to
the miniaturized package sizes of 3 × 3 mm, integration into high-priced products, casings, consumable
materials, etc., can be achieved in a discreet way. Furthermore, the integrated CIPURSETM chip enables
not only the anti-counterfeiting use-case, but also micropayment, ticketing, access control, and password
storage in a secured way. Therefore, this miniaturized contactless authentication solution will open up
whole new fields of applications.

Security-related factors in extended UTAUT model for NFC based mobile payment in the restaurant industry
عوامل مرتبط با امنیت در مدل UTAUT توسعه یافته برای پرداخت تلفن همراه مبتنی بر NFC در صنعت رستوران-2017 This study aims to provide an integrated model that examines the determinants of near-field commu- nication (NFC) based mobile payment (MP) technology acceptance in the restaurant industry. The pro- posed model, which combines the unified theory of acceptance and use of technology (UTAUT) and technology acceptance model (TAM), was tested via structural equation modeling (SEM) by using data collected from 412 restaurant customers. The study results indicated that the proposed model provides approximately 20% greater explanatory power and predictive accuracy than the original UTAUT model and demonstrates strong evidence of the effects of risk, security, and trust on customers intentions to use NFC-based MP technology in restaurant settings. In addition, considering the total effect, attitude, security, and risk have the most substantial impact on customers’ behavioral intentions. The study results further demonstrate that risk, security, and trust are also important determinants, with direct and in- direct impacts, of other critical constructs (i.e., effort expectancy, hedonic and utilitarian performance expectancy, attitude, and intention). The empirical findings provide valuable theoretical contributions for researchers and practical implications for restaurant operators and technology vendors by explaining the reasons as to why the NFC-based MP is not popular in North American restaurants.© 2017 Elsevier Ltd.

A distributed framework for health information exchange using smartphone technologies
یک چارچوب توزیع برای تبادل اطلاعات سلامت با استفاده از فن آوری های گوشی های هوشمند-2017 Nationwide health information exchange (NHIE) continues to be a persistent concern for government
agencies, despite the many efforts and the conceived benefits of sharing patient data among healthcare
providers. Difficulties in ensuring global connectivity, interoperability, and concerns on security have
always hampered the government from successfully deploying NHIE. By looking at NHIE from a fresh per
spective and bearing in mind the pervasiveness and power of modern mobile platforms, this paper pro
poses a new approach to NHIE that builds on the notion of consumer-mediated HIE, albeit without the
focus on central health record banks. With the growing acceptance of smartphones as reliable, indispens
able, and most personal devices, we suggest to leverage the concept of mobile personal health records
(PHRs installed on smartphones) to the next level. We envision mPHRs that take the form of distributed
storage units for health information, under the full control and direct possession of patients, who can
have ready access to their personal data whenever needed. However, for the actual exchange of data with
health information systems managed by healthcare providers, the latter have to be interoperable with
patient-carried mPHRs. Computer industry has long ago solved a similar problem of interoperability
between peripheral devices and operating systems. We borrow from that solution the idea of providing
special interfaces between mPHRs and provider systems. This interface enables the two entities to com
municate with no change to either end. The design and operation of the proposed approach is explained.
Additional pointers on potential implementations are provided, and issues that pertain to any solution to
implement NHIE are discussed.

A wireless potentiostat for mobile chemical sensing and biosensing
پتانسیواستات بی سیم برای سنجش شیمیایی همراه و biosensing-2015 Wireless chemical sensors are used as analytical devices in homeland defence, home-based healthcare, food logistics and more generally for the Sensor Internet of Things (SIoT). Presented here is a battery- powered and highly portable credit-card size potentiostat that is suitable for performing mobile and wearable amperometric electrochemical measurements with seamless wireless data transfer to mobile computing devices. The mobile electrochemical analytical system has been evaluated in the laboratory with a model redox system – the reduction of hexacyanoferrate(III) – and also with commercially available enzymatic blood-glucose test-strips. The potentiostat communicates wirelessly with mobile devices such as tablets or Smartphones by near-field communication (NFC) or with personal computers by radio-frequency identification (RFID), and thus provides a solution to the ‘missing link’ in connectivity that often exists between low-cost mobile and wearable chemical sensors and ubiquitous mobile com- puting products. The mobile potentiostat has been evaluated in the laboratory with a set of proof-of- concept experiments, and its analytical performance compared with a commercial laboratory po- tentiostat (R2 ¼ 0.9999). These first experimental results demonstrate the functionality of the wireless potentiostat and suggest that the device could be suitable for wearable and point-of-sample analytical measurements. We conclude that the wireless potentiostat could contribute significantly to the ad- vancement of mobile chemical sensor research and adoption, in particular for wearable sensors in healthcare and sport physiology, for wound monitoring and in mobile point-of-sample diagnostics as well as more generally as a part of the Sensor Internet of Things.& 2015 Elsevier B.V.
