Fully Integrated Digitally Assisted Low-Dropout Regulator for a NAND Flash Memory System

In this paper, a fully integrated digitally assisted low-dropout regulator (LDO) for a NAND flash memory system is proposed and verified using 500 nm I/O CMOS transistors. By combining an amplifier (AMP)-based LDO with a comparator (CMP)-based LDO, the proposed LDO achieves both fast load response in the transient state and accurate regulation in the steady state, which are advantages of the CMP-based LDO and AMP-based LDO, respectively. Moreover, loop frequency stability is satisfied in a wide range of load currents between 0 and 150 mA by using the simple structure of the <inline-formula><tex-math notation="LaTeX">$g_{m}$</tex-math></inline-formula>-boost cell to insert an auxiliary path. For an input voltage range of 2.3–3 V and an output voltage of 2.1 V, the measured output droop is 225 mV for a 150 mA load step in the load transition time of 20 ns with the total bias current of <inline-formula><tex-math notation="LaTeX">$81\,\mu {\rm{A}}$</tex-math></inline-formula>. The fabricated prototype chip occupies <inline-formula><tex-math notation="LaTeX">$160\,\times \,610\,\mu {\rm{m}}^{2}$</tex-math> </inline-formula> with an on-chip output capacitor of 2 nF.
Physics-based modelling and animation of saccadic eye movement

In this paper we present a new approach in producing realistic saccade eye movement animations by incorporating anatomical details of the oculomotor system into the dynamics of the eye model. Unlike abstract models of the eye motor behaviour, we make use of a biomedical framework to effectively model the eye globe along with the three extraocular muscle pairs in efficient detail, that the application of the corresponding muscle activation signals, naturally results in realistic motions. That way, we avoid the need of explicitly providing trajectory information, and therefore simplify the process of eye animation. Regarding the calculations of the muscle activation signals needed to drive the animation in a way that imitates a real human eye, we are based on existing knowledge about the way that the nervous system utilizes the extraocular muscles during saccades.
Control of quantum systems by dissipation

Quantum computer could contribute a great deal in many areas. An important use of quantum computer for physicists is quantum simulation, which is presented in the rst part of the seminar. The greatest obstacle in quantum computation is decoherence, which is induced by environment. Therefore, it is important to be able to control the coupling of system with environment. The idea of dissipative quantum state preparation and dissipative quantum computing is to use such coupling for obtaining pure states of quantum systems or even result of quantum computation.
COMPLEX FLUID MIXING IN MICROFLUIDIC DEVICES : THEORY AND SIMULATIONS

Micro and nano-fluidic mixing is now an important area of scientific research because of its applications in significant areas such as electrophoresis systems, chemical and bio-chemical synthesis. Fluid flow at these small dimensions is necessarily laminar and, as such, dominated by diffusion which is extremely slow. Furthermore, more realistic applications deal with viscoelastic fluids where it is well known dynamics are significantly slower than for simple fluids. In this study we consider how mixing can be enhanced by using some clever techniques such as chemical patterning of the micro-fluidic tube walls for non-Newtonian and viscoelastic fluids. We use both continuum modelling and molecular dynamics simulations to describe these slow flows and outline some important ways in which fluid mixing can be promoted in these devices.
A Network-Based Implementation of an Aerial Robotic System

This paper describes a unique and generic approach to solving complex aerial robotics missions. This approach is based on an intelligence system that is distributed over a remote vehicle network. In this paper a specific implementation of this generic approach is designed to fulfill the International Aerial Robotics Competition requirements. This design consists of a four level remote vehicle network comprised of a base station, a transport vehicle, a delivery vehicle and a payload vehicle. The specific design decisions for each of these vehicles are discussed throughout this paper.
Field measurements of Tropical Storm Aere (1619) via airborne GPS‐dropsondes over the South China Sea

In the past two decades, Global Positioning System (GPS)‐dropsonde has been developed as an effective tool to explore the internal structures of tropical cyclones (TCs). To facilitate the short‐term forecasting of the TCs' intensity and track over the Hong Kong Flight Information Region (HKFIR), Hong Kong Observatory (HKO) launched in 2016 reconnaissance campaigns by using airborne GPS‐dropsondes. On October 7, 2016, when Tropical Storm Aere (1619) got close to Hong Kong, 10 dropsondes were released from a reconnaissance aircraft at 10 km altitude to sample the TC at different storm‐relative positions. This offers a valuable opportunity to examine the functional performance of the dropsonde system. In the study, the validity of dropsonde measurements is first examined, mainly by comparing the results with those collected contemporaneously by radiosonde balloons from a nearby station. Observational results of the structural characteristics are then discussed. Evidence was observed for the invasion of the storm's inner structure by background atmosphere, which was unfavourable for the intensification of Aere in the following time. Meanwhile, a height‐resolving model of the TC's pressure field is proposed. It is also observed that the parachutes of two dropsondes failed to deploy during the descending period. The results presented here are expected to provide useful information for a better understanding of the in‐situ measurements from dropsondes deployed over the HKFIR, and for advancing the knowledge on TC's inner structure.
FACTORS THAT PROMOTE EXPORT CONVERGENCE: A SPATIAL ANALYSIS IN ROMANIA

This paper combines two topics of high interest for regional development in Romania - international trade and real convergence – in an attempt to better understand their recent trends. Aiming to use the most appropriate and up to date instruments for our analysis, we tested the conditional beta convergence model both in its classic regression specification and in the spatial regression framework that allowed us to address properly the territorial dimension of the phenomenon by accounting for spatial autocorrelation in exports. Although the hypothesis of sigma convergence in export flows does not hold, we found a significant process of conditional beta convergence among the Romanian counties, for various model specifications and time intervals. Our results confirm that the prerequisites for real convergence in Romanian exports are already met and sigma convergence might appear in the future.
Dietary assessment in children and adolescents: issues and recommendations.

The assessment of dietary intake in children and adolescents is of great interest for different purposes. The characteristics of each developmental stage and associated cognitive abilities are two factors that influence the ability of children to provide valid and reliable information on food consumption. The ability to remember, limitations of vocabulary or the ability to identify different foods are some of the relevant aspects. In addition, often parents or caregivers provide surrogate information and their degree of knowledge depends on the time they spend with the child and on whether they share meals. As children grow they become more independent and increasingly spend more time away from their parents. Children also have limitations to recognize food models and photographs and associate them with different amounts of food consumed. On the other hand, often children and adolescents perceive long interviews or self-administered questionnaires they as long and boring. The use of new technologies is contributing to the development of new tools adapting dietary assessment the methods to the cognitive abilities of children, introducing gaming environments and narrative structures that attract their interest and improve the quality of information they report.
Diversity of Pachyrynchini ( Coleoptera : Curculionidae : Entiminae ) in Mt . Kiamo , Malaybalay , Bukidnon , Mindanao , Philippines

A field survey of weevils of the tribe Pachyrynchini (Coleoptera: Curculionidae: Entiminae) was conducted in Mt. Kiamo, Malaybalay, Bukidnon last December of 2015 to December, 2016. Field sampling was performed using a combination of belt transect, opportunistic and random sampling techniques. Field investigations were done in two vegetation types with elevation from 750-1,500 meters above sea level (masl), which include the lower montane (750-1,000 masl) and upper montane (1,0001,500 masl) forests. Baseline data on species richness and local distribution were documented. A total of 239 individuals belonging to 20 species and 3 genera viz., Pachyrhynchus, Homalocyrtus and Metapocyrtus were collected from the two vegetation types. The upper montane forest had higher species richness with 12 species as compared to the lower montane forest with 10 species. Only 2 species were shared between the lower and upper montane. Species composition of Pachyrynchini in Mt. Kiamo is unique from that of Mt. Apo and Mt. Malindang. In addition, recent distribution records of the Pachyrynchini found in Mt. Kiamo identified to the species level were provided. This is the only update on distributional record of these species since Schultze monograph in 1923. The results of the survey show that the richness of Pachyrynchini in Mt. Kiamo is high despite the anthropogenic disturbances it experiences. It is recommended that this mountain ecosystem be declared as protected area in order to conserve the endemic and threatened species and ecosystem as a whole.
Identifying student resources in reasoning about entropy and the approach to thermal equilibrium

[This paper is part of the Focused Collection on Upper Division Physics Courses. ] As part of an ongoing project to examine student learning in upper-division courses in thermal and statistical physics, we have examined student reasoning about entropy and the second law of thermodynamics. We have examined reasoning in terms of heat transfer, entropy maximization, and statistical treatments of multiplicity and probability. In this paper, we describe student responses in interviews focused on the approach of macroscopic systems to thermal equilibrium. Our data suggest that students do not use a single simple model of entropy, but rather use a variety of conceptual resources. Individual students frequently shifted between resources, in some cases leading to contradictory predictions. Among the resources that students employed were some that have been previously described in the literature, including inappropriate use of conservation. However, our results suggest that student use of resources connected to disorder are neither simple nor monolithic. For example, many students used a previously unreported association between the equilibrium state of a system and an increase in order, rather than disorder.
Towards Reducing Last-Level-Cache Interference of Co-Located Virtual Network Functions

Network Function Virtualization (NFV) aims to virtualize compute resources for packet processing in order to gain flexibility and reduce costs. In order to increase the resource utilization, multiple VNFs are co-located on one single server. Current virtualization techniques do not fully isolate all resources, thus co-location of VNFs causes interference effects. It has been shown that these interference effects can degrade the performance of Virtualized Network Functions (VNFs) in terms of throughput and delay severely. In this work we aim to gather the potential that lies in reduction of the interference due to the shared Last Level Cache (LLC). CPU caches are used to improve the access times to memory that is needed regularly for the execution of a program. Intel Cache Allocation Technology (CAT) provides the means to allocate the cache and isolate VNFs from each other. The results show that the scheduler can decrease the CPU utilization by up to 20%. We can show which factors influence the gain of LLC scheduling in NFV deployments. In order to show this we propose a scheduler which optimally allocates the LLC in order to reduce the maximum CPU utilization of all cores.
From Instrument to Policy: Observing the Meaning Process to Make a Decision

From 1950, a lot of researchers try to understand what is policy, how to define it and what kind of knowledge we can produce about it. When Harold Lasswell in 1942 proposed to develop the policy science, he established a strong connection between the development of policy sciences and democracy. He deemed that there was a complementary relationship between knowing policy and the political system. With policy analysis at the end of the century, two kinds of knowledge have been developed. First, knowledge about the substance of policy, the different kind of instruments which compose it, their effects, meaning and goals. Second, knowledge of the policy process, to understand how and why policy changes. Each knowledge has its own dynamics. But the problem is always the difficulty to link the two kinds of knowledge: knowledge of instrument analysis and knowledge of policy dynamics analysis. We can choose between work which understands the substance of policy but does not examine policy dynamics, and work about policy dynamics that does not take into account the specific substance of policy. Finally, a lot of researchers who produce knowledge of instruments never understand why their knowledge has so little influence. The paper aims to review the complex relationship between knowledge of instruments and knowledge of policy dynamics, and proposes to open a new way by considering the role of knowledge of instruments inside policy dynamics. The main idea is to focus on the discursive process of actors who transform instruments into policy by making sense of the instruments, and to illustrate this by some empirical examples.
Dynamic Aggregation of Virtual Addresses in TLB Using TCAM Cells

In this paper, we propose dynamic aggregation of virtual tags in the Translation Lookaside Buffer (TLB) to increase its storage capacity without increasing the size of the tag array. To support dynamic aggregation, we incorporate a few Ternary-CAM (TCAM) cells into the TLB tag array. The modified TLB architecture demonstrates a compression scheme that increases TLB reach with negligible overhead and no access time penalty. The performance of the proposed TLB architecture is evaluated using SPEC CPU2000 benchmarks. Simulation results indicate a significant reduction in miss ratios, nearly 100% reduction is achieved in several benchmarks, and as much as a 46% increase in IPC (Instructions per cycle) is obtained when compared to a conventional TLB with the same number of tag entries. We also evaluate the performance of our tag compressed TLB against the performance of a conventional TLB that contains an equivalent number of virtual to physical address translations. Our results show that TCAM based compression is able to achieve nearly the same system performance as the large conventional TLB while consuming on average 38% less energy and 42% less area; thus illustrating that tag compression is a more attractive solution for improving TLB performance than simply increasing the size of the TLB.
Mathematical and Сomputational Modelling of MHD Effects in Entrained Droplets of Slag and Metal

A common mode of operation for electric smelting furnaces involves the availability of an open arc above the molten bath of process material. The plasma arc consists of a high-velocity, high-temperature jet of ionized gas, which imparts considerable mechanical stirring to the area in which it interacts with the surface of the bath. This stirring can result in significant inter-mixing and entrainment of the liquid phases in the bath, particularly in the vicinity of the arc attachment zone. Substantial electric current is also passed through this zone, either down through the slag and metal into the anode in the case of DC, or through the bath volume to the other electrodes in the case of AC. The present study aims at quantifying the magneto-hydrodynamic (MHD) forces that result from the passage of electric current through and around droplets of one phase entrained in another. These forces can result in both intraparticle and inter-particle fluid dynamics, and generally act in opposition to surface tension and other forces. The OpenFOAM open-source framework is used to develop computational solvers based on the mathematical formulation of the problem. These tools are then applied to study the effect of current densities, diameters, interfacial surface tensions and other parameters on the droplet dynamics.
The Effect of Financial Status on Consumer-Perceived Anthropomorphism and Evaluation of Products with Marketer-Intended Anthropomorphic Features

The present research distinguishes between marketers’ efforts to design products with human features and consumers-perceived anthropomorphism. Four studies assessed the hypothesis that consumers-perceived financial status moderates their expectations about how an anthropomorphized product would treat them, affecting their motivation to perceive the marketer-intended anthropomorphic features as signaling human agency and their evaluations of the anthropomorphized entity. In study 1, participants who felt rich expected a humanized entity (a self-driving car) would prioritize their well-being over those of others, whereas people in the perceived poor condition expected the opposite. The results of studies 2 and 3 indicate that participants who perceived themselves to be financially well off evaluated a product high in marketer-intended anthropomorphic features more positively (1) than a less anthropomorphic product and (2) than participants who felt financially worse off did. However, when participants adopted an unusual expectation about treatment in the marketplace, when they expected the poor to be treated better than the rich, we observed the reverse pattern (study 4). Consumer-perceived anthropomorphism of the marketer-designed product mediated these findings. Findings support the view that a readily measured variable—financial status—moderates consumer responses to marketer-intended anthropomorphic features.
Perspectives of Mothers in Farmworker Households on Reducing the Take-Home Pathway of Pesticide Exposure

Farmworkers carry pesticide residue home on their clothing, boots, and skin, placing other household members at risk, particularly children. Specific precautions are recommended to reduce this take-home pathway, yet few studies have examined the perspectives of farmworkers and other household members regarding these behaviors and the reasons for or against adoption. The authors conducted semistructured interviews with 37 Mexican/Mexican-American women in farmworker households to explore the family and cultural context in which pesticide safety practices are performed and to identify factors that facilitate or hinder their adoption. Whereas women could describe the take-home pathway, they were less able to connect it with their family’s susceptibility to pesticide exposure. Women experienced difficulty integrating the prevention behaviors into their everyday lives because of competing responsibilities, conflicts with their husbands’ intentions and with cultural health beliefs, perceived lack of control, and community barriers that interfered with women’s motivations. Implications for practice are discussed.
Tendencies of Mining Technology Development in Relation to Deep Mines

Mineral demand rapidly increases; as a result, underground mining activities gradually dig into the earth’s crust to deeper levels. For instance, the depth of coal mines has reached 1500 m, whereas the depth of mines for nonferrous metals has already achieved around 4500 m. Deep mining faces a number of technical and environmental challenges, first of all, great rock mass stresses, high temperature and long winding distance. The traditional technologies are hardly capable to provide the development and extraction efficiency and safety. That is why the need in developing and implementation of new modern mining technologies arose. In roadheading, TBM (tunnelboring machine) method is gradually introduced. A TBM combines the functions of rock breaking, support installation, mucking and conveying rock. In mining industry, smart mining based on mechanized and automated mining methods is successfully implemented at coal mines. Besides, a technical concept of fluidized mining for deepseated mineral resources (6000 m and more) was proposed. This paper presents the review of the current global status of deep mining and highlights some of the newest technological achievements in roadheading and the mineral extraction processes.
Platelet Function Testing: Quality Assurance

Platelet function tests are widely used for the diagnosis of platelet disorders. In recent years there has been increasing interest in the use of platelet function tests to monitor antiplatelet drug therapy. Quality assurance is important to optimize the performance of laboratory assays but it has not been widely applied to platelet function tests. This deficiency likely reflects the need to use freshly collected blood samples for platelet function tests, and the complex, time-consuming nature of some assays such as aggregation studies. Platelet function testing lacks guidelines, is poorly standardized between laboratories, and rarely is evaluated by internal and external quality assurance exercises. The sensitivity, specificity, and diagnostic utility of some newer, simplified assays of platelet function have been evaluated in a range of clinical settings but corresponding quality assurance data for many established as well as emerging platelet function assays are lacking. Quality assurance issues relevant to testing platelet function are reviewed in this article, with a focus on their application to established and to new and emerging tests.
PLZT-modified relaxor piezoelectric ceramic system for medical diagnostic applications

The piezoelectric ceramic system [Pb0.978−yLa0.012Ba0. 01Sry][(Zr0.534Ti0.466)0.987Nb0. 008]O3 (PLBSZNT) has been fabricated for use in medical diagnostics applications. The fundamental pre-requisites are high-density, high dielectric constant and high piezoelectric properties that serve as compatible ceramic materials for medical diagnostic applications. It is essential for sensitive transducers that the piezoelectric ceramics must efficiently convert between electrical and mechanical energy, and so the electromechanical coupling coefficients should be high, as the fabrication process of tiny elements for medical arrays must be carried out without damaging the material and its properties. In our study, Sr-modified PLBZNT had shown single ferroelectric tetragonal phase. An analysis of different Sr doping concentration is reported, and the high dielectric permittivity, low dielectric loss along with high electromechanical properties indicate that PLBSZNT is suitable for medical diagnostic applications as well as sensors and actuators.
