TCP and MP-TCP in 5G mmWave Networks

Future 5G networks will likely include mmWave radio access communication links, because of their potential multi-gigabit-per-second capacity. However, these frequencies are characterized by highly dynamic channel conditions, which lead to wide fluctuations in the received signal quality. This article explains how the end-to-end user experience in mobile mmWave networks could be affected by a suboptimal interaction between the most widely used transport protocol, TCP, and mmWave links. It also provides insights on the throughput-latency tradeoff when Multipath TCP (MP-TCP) is used judiciously across various links, such as Long-Term Evolution (LTE) and mmWave.
Análise Comportamental de Problemas de Interação Social de Indivíduos com Psoríase

Psoriasis is a chronic skin disease that affects individuals of both genders beginning from the second decade of life. Besides physical discomfort due the symptoms like itching and scaling, interpersonal difficulties are commonly reported by patients to their doctors. The unaesthetic aspect of psoriatic lesions usually affects the patients´ ability to deal with negative reactions from other people, in several contexts of social interactions. Therefore, individuals try to escape from situations where they are at risk of being physically exposed, in an attempt to avoid being stared at and comments on their appearance. They also tend to cover lesions, using cosmetic camouflage or protective clothes like long sleeves, skirts and caps, even on hot days. In this article, the authors evaluate how behavior analysis explains social behavior and they discuss, using this approach, how environmental variables can control social behavior, changing the probability of its occurrence in different social contexts. Keywords: psoriasis; social interactions; behavior analysis.
CONTRAST SENSITIVITY DECLINE WITH AGEING: A NEURAL OR OPTICAL PHENOMENON? *

Abstract— Previous studies of contrast sensitivity changes with age have produced conflicting results. Most recent reports indicate that, with increasing age, contrast sensitivity at medium and high spatial frequencies decreases. Whether this is caused by reduced retinal illumination due to senile pupillary miosis and increased lens absorption, by the greater light scatter of the aged eye or by retinal and neural celt loss and degeneration is also in doubt. We measured the contrast sensitivity functions of 16 young (mean age 21.5 ± 2.7 years) and 16 older (mean age 72 ± 4.3 years) subjects with normal healthy eyes, using a modified Rodenstock retinometer and a monitor‐based computer system. The former method bypasses the effects of the optical media to measure the contrast sensitivity function of the retinal and neural system alone, while the latter measures the contrast sensitivity function of the whole visual system, including media. The results show the older group to have significantly lower contrast sensitivity at medium (4 c deg‐1, p < 0.1) and high (10.6 c deg‐1p < 0.001; 16.5 c deg‐1, p < 0.001) spatial frequencies. They also suggest that this is due primarily to retinal and neural changes with age, with optical factors having a slight effect at the highest spatial frequency only.
Rethinking Ethics Review as Institutional Discourse

In this article, the authors trace the emergence of an institutional discourse of ethical research and interrogate its effects in constituting what ethical research is taken to be and how ethical researchers are configured. They illuminate the dissonance between this regime of truth and research practice and the implications for the injunction to respect others, illustrating their case with instances from their interview study with anorexic teenage girls. The authors propose that conceptualising the regulation of research ethics as an institutional discourse opens up the possibility for asserting counterdiscourses that place relational ethics at the center of moral decision making in research.
Depression and severity of substance dependence among heroin dependent patients with ADHD symptoms

BACKGROUND AND OBJECTIVES Comorbid attention deficit hyperactivity disorder (ADHD) symptoms are highly prevalent among heroin-dependent patients. We aim to investigate differences in dependence severity, depression, and quality of life between heroin-dependent patients with and without ADHD-screened positive. METHODS Heroin-dependent participants (n = 447) entering methadone maintenance treatment were divided into ADHD-screened positive (ADHD-P) and ADHD-screened negative (ADHD-N) groups according to scores of Adult ADHD Self-Report Scale (ASRS). Mini-International Neuropsychiatric Interview was used to identify current and lifetime depressive episodes and suicidality. Substance use disorder, depression, family support, and quality of life in two groups were also assessed. RESULTS About 7.8% (n = 35) scored 24 or higher of ASRS indicating highly likely Adult ADHD. More heroin-dependent patients of ADHD-P had a current depressive episode (p = .02). They had higher Center for Epidemiological Studies Depression (CESD) scores (p = .003), and more severe heroin dependence (p = .006). Poorer family support and quality of life in physical, and psychological domains were found in patients of ADHD-P compared to ADHD-N. DISCUSSION AND CONCLUSIONS Heroin-dependent patients of ADHD-P represent a vulnerable minority. They were comorbid with regard to depression, greater substance dependence severity, and poorer quality of life. SCIENTIFIC SIGNIFICANCE Assessment for ADHD symptoms in heroin-dependent patients may be indicated for the effective management of the complex problems of these patients. (Am J Addict 2017;26:26-33).
Hardware-in-loop simulation of autonomous relative navigation for noncooperative spacecraft

This paper presents a hardware-in-loop simulation to validate the autonomous relative navigation algorithm for noncooperative target spacecraft. The algorithm was based on the closed-form solution of linear Clohessy-Wiltshire (C-W) equations and nonlinear measurement equations. The navigation filter, a 6-state extended Kalman filter, processes angle measurements from an optical navigation camera along with range measurement from laser rangefinder data to estimate the relative position and velocity between two spacecrafts. A 15-degree-of-freedom closed-loop kinemical simulation platform was set up based on attitude and relative position motion. The filterpsilas performance was evaluated and tested by running a hardware-inloop simulation experiment containing the relative measurement sensors. The experimental results validate the proposed algorithm.
Ways in Which Governing Bodies Contribute to School Improvement: Findings from a Pilot Project.

ABSTRACT Legislation over the last 10 years has increased considerably the responsibilities of school governors but there has been little research into their role in bringing about school improvement. This paper reports upon a pilot project designed to set the parameters and criteria for a more detailed and extensive study into this area. Based upon the data gathered, it is possible to suggest some ways in which governing bodies can enhance the conditions for improvement.
The dynamics of the collective competencies among working groups: the case of General Shutdown Maintenance in a Brazilian Petrochemical Company

The competitive scenario in recent decades has imposed increasing levels of complexity and interdependence to companies, which try to respond to this challenge providing some organizational changes, such as collective arrangements. This article aims to understand the emerging collective competencies based on the mobilization of different working groups to make the turnaround maintenance (TM) possible, in a Brazilian petrochemical company. The turnaround maintenance is characterized as a large network of interdependent services, which requires advance planning of 30 months, occurring during 30 days and hosting a contingent of 6400 people from within the company in addition to outside contractors. The theoretical basis for this study focuses on addressing the social competencies approach having as the main contributors American, French and Swedish authors. These authors analyze the collective competencies focused on sensemaking (Weick, 1993) and individual knowledge based on a common goal For this end we use the case study method (Yin, 1994) having as a basis four distinct and complementary research stages that show the evolution of the research itself. (1) The initial exploratory phase aimed to understand the collective competencies as a process issue, based on the following elements: sensemaking, shared understanding, action and scope. (2) The second phase analyzed the elements of collective competencies considering the results produced, identified as the macro level, based on the following elements: safety, quality, time and cost. (3) The descriptive relational phase aimed to analyze the relations of complementarity among the elements of the collective competencies, showing the relationships among the elements of the micro level, the macro level and the micro and macro levels. (4) Finally, the validation of the data was held in a meeting with the Steering Committee of the TM, in order to validate the research findings with those responsible for the event. As a data collection instrument we use semi-structured interviews, focus groups, non-participant observation and secondary data. We also use the content analysis (Bardin, 1977) and Matrix Coding Nvivo (Flick, 2002) to analyze the data. The research findings show that the notion of collective competencies can be understood from two perspectives that are both different and complementary at the same time-process and outcome views. Regarding the process view, the collective competencies are seen as a dynamic capability based on the interaction among different working groups creating the mobilization of additional powers from the following elements, which constitute the collective competencies: sensemaking, shared understanding, action and scope. …
A hierarchical approach to the formal verification of embedded systems using MDGs [microcontrollers]

With the increasing emergence of mixed hardware/software systems, it is important to ensure the correctness of such a system formally, particularly for real-time and safety critical applications. We present a hierarchical approach to modeling and formally verifying an embedded system at higher levels of abstraction, using Multiway Decision Graphs (MDGs). We demonstrate our approach on the embedded software for a mouse controller application on a commercial microcontroller (PIG 16C71), using the MDG verification tools. Inconsistencies in the assembly code with respect to the specification, as published in the application notes of the manufacturer, were uncovered through our experiments.
Channel for reading

Letter identification is mediated by just one spatial frequency channel (Solomon and Pelli, 1994). But what about reading? We wondered whether larger features, e.g. words, at lower spatial frequencies are used when reading text. The demo shows text on a background of narrowband noise varying in spatial frequency from top to bottom. Try reading it. You read quickly at the top, slow down in the middle, and speed up again at the bottom. The middle frequencies impair reading most, just as found with letter identification (Majaj et al. 2002). No channel tuned to words was revealed.
Planar Quantum Mechanics: an Intriguing Supersymmetric Example

After setting up a hamiltonian formulation of planar (matrix) quantum mechanics, we illustrate its effectiveness in a non-trivial supersymmetric example. The numerical and analytical study of two sectors of the model, as a function of 't Hooft's coupling λ, reveals both a phase transition at λ = 1 (disappearence of the mass gap and discontinuous jump in Witten's index) and a new form of strong-weak duality for λ→1/λ.
The Hardware Design and Implementation of a Signal Reconstruction Algorithm Based on Compressed Sensing

A fast and reliable signal reconstruction algorithm is the core part of the compressed sensing (CS) theory. As a reconstruction algorithm, interior point method has a high precision but it is time-consuming and needs large computation, so it is difficult to meet the actual needs. In view of the above problems, in this paper we propose a design for interior point method that is based on the Field Programmable Gate Array (FPGA )hardware platform, which is about the solution of linear equations that have the largest amount of computation. The array structure of the conjugate gradients (CG) coprocessor completes the main operations, and the parallel and pipeline coprocessor effectively take advantage of the inherent parallelism of the algorithm and the parallel structure of FPGA. Thus, it has greatly improved the processing speed.

Incidence, determinants and significance of delayed clearance of serum HBsAg in chronic hepatitis B virus infection: A prospective study

To investigate the incidence, determinants and significance of delayed clearance of serum HBsAg in chronic hepatitis B virus infection, a prospective follow‐up study was conducted in two consecutive groups of patients. Group I consisted of 984 patients (859 men and 125 women) with biopsy‐proven chronic type B hepatitis, whereas group II consisted of 1,598 asymptomatic chronic carriers (998 men and 600 women) with normal serum aminotransferase activity. During a mean follow‐up period of 4.0 ± 2.3 yr, 19 patients (1.9%) of group I cleared HBsAg from their serum, whereas 35 patients (2.2%) in group II did so in a mean follow‐up period of 2.7 ± 1.4 yr. The annual incidence of delayed serum HBsAg clearance was 0.5% in group I and 0.8% in group II (p < 0.02). The cumulative probability of HBsAg clearance was also higher in group II than in group I (p <0.007). Antibodies to HBsAg developed in 9 patients (47.4%) with chronic hepatitis and in 11 (31.4%) asymptomatic carriers who cleared serum HBsAg. Those who were HBeAg negative and those older than 40 at entry and those who exhibited cirrhosis during follow‐up had a higher incidence of delayed HBsAg clearance. Gender, initial histological changes and hepatitis delta virus infection did not influence the occurrence of HBsAg clearance. Serum HBV DNA was not detectable by slot‐blot hybridization but was still detectable by polymerase chain reaction in serum specimens collected within 1 yr of HBsAg clearance. Liver biopsy performed later in 10 patients showed no significant hepatitis activity or tissue HBV DNA, HBsAg or HBcAg. The results suggest that the incidence of delayed clearance of HBsAg during chronic HBV infection is low. HBeAg status, age of patients and development of cirrhosis are determinants for HBsAg clearance. (HEPATOLOGY 1991;13:627–631.)
A microwave breast imaging system using elliptical uniplanar antennas in a circular-array setup

Microwave tomography has attracted significant research interest as it offers a non-ionizing diagnostic technique for breast cancer. A microwave breast imaging (MBI) system comprises an array of antennas, which illuminates the tissue and measures the scattered energy in order to spatially allocate the dielectric permittivity and conductivity of the tissue. The radiating elements of a MBI system should be compact and wideband. This paper describes an elliptical uniplanar antenna 40 mm × 50 mm in size that operates in the 1.53-3.33 GHz range when placed against a breast phantom. The antenna is used as the radiating element in a circular-array setup around a hemispherical phantom. Simulated and measured data from the proposed array are presented, which show satisfying agreement and system performance.
RETHINKING THE ROLE OF TRANSPORTATION IN TOURISM

Transportation and travel can be discussed without taking tourism into consideration, but tourism cannot thrive without travel. Transportation is an integral part of the tourism industry. It is largely due to the improvement of transportation that tourism has expanded. The impacts on the ecology, degradation of destination sites, tourist experience, and economy has called for a better management of resources. In biodiversity-rich areas, opening of sensitive and fragile areas through improved infrastructure and service may prove detrimental to the ecology of the place. In the light of such issues, it is important to re-think the role of transportation in areas such as these. Though careful planning of the components of the destination is done to ensure sustainability, transportation is seldom considered in the process and due to this a number of biodiversity-rich areas have been destroyed due to the easy access.
Non-local scrambling: the equivalence of TAG and CCG revisited

It is well known that standard TAG cannot deal with certain instances of longdistance scrambling in German (Rambow, 1994). That CCG can deal with many instances of non-local scrambling in languages such as Turkish has previously been observed (e.g. by Hoffman (1995a) and Baldridge (2002)). We show here that CCG can derive German scrambling cases which are problematic for TAG, and give CCG analyses for other German constructions that require more expressive power than TAG provides. Such analyses raise the question of the linguistic significance of the TAG-CCG equivalence. We revisit the original equivalence proof, and show that a careful examination of the translation of CCG and TAG into Indexed Grammar reveals that the IG which is strongly equivalent to CCG can generate dependencies which the corresponding IG obtained from an LTAG cannot generate.
From impact evaluations to paradigm shift: a case study of the Buenos Aires Ciudadanía Porteña conditional cash transfer programme

In response to the economic and social crises in 2001–2002, the Buenos Aires City Government opted for a cash transfer programme, the Ciudadanía Porteña: Con Todo Derecho, or CPP, in 2005. This case study looks at three impact evaluations of the programme and how they were used. The evaluations were designed with a dual purpose: (i) to determine how the programme could be made more efficient and thus obtain its goals, and (ii) to build consensus and legitimacy about the strategy of cash transfers in general. The most significant change resulting from the evaluations was the creation of the ‘To study is to work’ component, as of a recommendation made in the first evaluation report of the CPP. In addition, cash benefits for children and teenagers in school were increased and more outreach to teenage mothers was added to help them find childcare options. In addition, there have been changes to the culture of evaluation within the City Government: the evaluations generated immediate improvements in the programme and had significant spillover effects in terms of promoting a new culture of evaluation. Lessons about the connections between the impact evaluations and the CPP policy are (i) trust worthiness of the findings, through rigour and drawing on international expertise, gives legitimacy to study recommendation, (ii) it seems crucial to have a clear communication and dissemination strategy of the results, building understanding and ownership of the study amongst a broad range of stakeholders, (iii) emphasise lesson learning over accountability, and (iv) the evaluation reports should have highlighted more strongly the negative findings to allow further adjustments to address these problems.
Effects of Budgetary Goal Characteristics on Managerial Attitudes and Performance

This study presents an empirical study on the effects of budgetary goal characteristics on managerial attitudes and performance in two dimensions of goal clarity and goal difficulty. The results show that budget goal difficulty and budget goal clarity have significant effects on job-related and budget-related attitudes. Furthermore, budget goal difficulty is found to have a positive effect on managerial performance. High level of budget goal difficulty and budget goal clarity will lead to a high degree of budgetary incentives.
Assisting Static Compiler Vectorization with a Speculative Dynamic Vectorizer in an HW/SW Codesigned Environment

Compiler-based static vectorization is used widely to extract data-level parallelism from computation-intensive applications. Static vectorization is very effective in vectorizing traditional array-based applications. However, compilers’ inability to do accurate interprocedural pointer disambiguation and interprocedural array dependence analysis severely limits vectorization opportunities. HW/SW codesigned processors provide an excellent opportunity to optimize the applications at runtime. The availability of dynamic application behavior at runtime helps in capturing vectorization opportunities generally missed by the compilers. This article proposes to complement the static vectorization with a speculative dynamic vectorizer in an HW/SW codesigned processor. We present a speculative dynamic vectorization algorithm that speculatively reorders ambiguous memory references to uncover vectorization opportunities. The speculative reordering of memory instructions avoids the need for accurate interprocedural pointer disambiguation and interprocedural array dependence analysis. The hardware checks for any memory dependence violation due to speculative vectorization and takes corrective action in case of violation. Our experiments show that the combined (static + dynamic) vectorization approach provides a 2× performance benefit compared to the static GCC vectorization alone, for SPECFP2006. Furthermore, the speculative dynamic vectorizer is able to vectorize 48% of the loops that ICC failed to vectorize due to conservative dependence analysis in the TSVC benchmark suite. Moreover, the dynamic vectorization scheme is as effective in vectorization of pointer-based applications as for the array-based ones, whereas compilers lose significant vectorization opportunities in pointer-based applications. Furthermore, we show that speculation is not only a luxury but also a necessity for runtime vectorization.
