Authors: Викулин И.М. , Горбачев В.Э. , Курмашев Ш.Д.
Published: September 2017

Исследовано влияние эффективной концентрации задающей тип проводимости базовой области примеси и толщины базы на радиационную стойкость транзисторных термодатчиков. Получены зависимости прямого падения напряжения на эмиттерном переходе транзистора и коэффициента усиления по току от величины потоков электронов, нейтронов и gamma-квантов. Получено, что деградация прямого падения напряжения под воздействием ионизирующего облучения начинается при дозах почти на 2 порядка выше, чем коэффициента усиления по току, в зависимости от конструктивных особенностей транзистора. После отжига облученных потоком электронов структур наблюдается значительное улучшение воспроизводимости термочувствительного параметра, что повышает процент выхода годных приборов.

Web-Based Cognitive Remediation Improves Supported Employment Outcomes in Severe Mental Illness: Randomized Controlled Trial
Authors: Harris Anthony WF , Kosic Tanya , Xu Jean , Walker Chris , Gye William , Redoblado Hodge Antoinette
Published: September 2017

Background

Finding work is a top priority for most people; however, this goal remains out of reach for the majority of individuals with a severe mental illness (SMI) who remain on benefits or are unemployed. Supported employment (SE) programs aimed at returning people with a severe mental illness to work are successful; however, they still leave a significant number of people with severe mental illness unemployed. Cognitive deficits are commonly found in SMI and are a powerful predictor of poor outcome. Fortunately, these deficits are amenable to treatment with cognitive remediation therapy (CRT) that significantly improves cognition in SMI. CRT combined with SE significantly increases the likelihood of individuals with severe mental illness obtaining and staying in work. However, the availability of CRT is limited in many settings.

Objective

The aim of this study was to examine whether Web-based CRT combined with a SE program can improve the rate return to work of people with severe mental illness.

Methods

A total of 86 people with severe mental illness (mean age 39.6 years; male: n=55) who were unemployed and who had joined a SE program were randomized to either a Web-based CRT program (CogRem) or an Internet-based control condition (WebInfo). Primary outcome measured was hours worked over 6 months post treatment.

Results

At 6 months, those participants randomized to CogRem had worked significantly more hours (P=.01) and had earned significantly more money (P=.03) than those participants randomized to the WebInfo control condition. No change was observed in cognition.

Conclusions

This study corroborates other work that has found a synergistic effect of combining CRT with a SE program and extends this to the use of Web-based CRT. The lack of any improvement in cognition obscures the mechanism by which an improved wage outcome for participants randomized to the active treatment was achieved. However, the study substantially lowers the barrier to the deployment of CRT with other psychosocial interventions for severe mental illness.

Uwarunkowania rozwoju przedsiębiorstw rolnych nastawionych na produkcję zwierzęcą w warunkach konkurencji i globalizacji
Authors: Ziętara Wojciech
Published: September 2017

W opracowaniu przedstawiono ekonomiczne, społeczne, środowiskowe i administracyjne uwarunkowania rozwoju przedsiębiorstw rolnych, głównie z chowem trzody chlewnej i bydła. Wskazano czynniki ekonomiczne i organizacyjne skłaniające przedsiębiorstwa rolne do zwiększania skali produkcji. Czynniki ekonomiczne związane są z szybszym tempem wzrostu kosztów pracy w gospodarce narodowej i cen środków produkcji rolniczej od cen zbytu produktów rolnych. Czynniki organizacyjne wiążą się z rosnącymi wymogami przedsiębiorstw handlu i przetwórstwa rolnego w zakresie wielkości, jakości i terminowości dostaw. Wzrost skali produkcji w gospodarstwach może prowadzić do nadmiernego obciążenia środowiska i wzrostu uciążliwości z powodu odorów dla ludności na terenach wiejskich i w efekcie do sytuacji konfliktowych na tle społecznym. Ponadto występują bariery administracyjne utrudniające realizację inwestycji budowlanych związanych z rozwojem produkcji zwierzęcej.
Connected model for opportunistic sensor network based on Katz centrality
Authors: Shu Jian , Xu Lei , Jiang Shandong , Meng Lingchong
Published: September 2017

Connectivity is an important indicator of network performance. But the opportunistic sensor networks (OSNs) have temporal evolution characteristics, which are hard to modelled with traditional graphs. After analyzing the characteristics of OSNs, this paper constructs OSNs connectivity model based on time graph theory. The overall connectivity degree of the network is defined, and is used to estimate actual network connectivity. We also propose a computing method that uses the adjacency matrix of each snapshot. The simulation results show that network connectivity degree can reflect the overall connectivity of OSNs, which provide a basis for improving the OSNs performance.

Published: September 2017

There are many problems in traditional Distributed Denial of Service (DDoS) attack detection such as low accuracy, low detection speed and so on, which is not suitable for the real time detecting and processing of DDoS attacks in big data environment. This paper proposed a novel DDoS attack detection system based on Spark framework including 3 main algorithms. Based on information entropy, the first one can effectively warn all kinds of DDoS attacks in advance according to the information entropy change of data stream source IP address and destination IP address; With the help of designed dynamic sampling K-Means algorithm, this new detection system improves the attack detection accuracy effectively; Through running dynamic sampling K-Means parallelization algorithm, which can quickly and effectively detect a variety of DDoS attacks in big data environment. The experiment results show that this system can not only early warn DDoS attacks effectively, but also can detect all kinds of DDoS attacks in real time, with low false rate.
Building a lightweight testbed using devices in personal area networks
Authors: Xu Qiaozhi , Zhang Junxing
Published: September 2017

Various networking applications and systems must be tested before the final deployment. Many of the tests are performed on network testbeds such as Emulab, PlanetLab, etc. These testbeds are large in scale and organize devices in relatively fixed ways. It is difficult for them to incorporate the latest personalized devices, such as smart watches, smart glasses and other emerging gadgets, so they tend to fall short in supporting personalized experiments using devices around users. Moreover, these testbeds commonly impose restrictions on users in terms of when and where to carry out experiments making them clumsy or inconvenient to use. The paper proposes to build a testbed utilizing users? devices in their own personal area networks (PANs). We have designed and implemented a prototype, which we call PANBED. Our experiments show that PANBED allows users to set up different scenes to test applications using a home router, PCs, mobile phones and other equipment. PANBED is light weighted with a size less than 16 KB and it has little impact to the other functions of the PAN. The experiment results also prove the realism, effectiveness, flexibility and convenience of PANBED.
Non-equilibrium solidification and microsegregation in centrifugally cast high speed steel for rolls
Authors: Klancnik U. , Kosec B. , Mrvar P. , Medved J.
Published: September 2017

When regarding as-cast microstructures of highly alloyed metals, microsegregation of alloying elements is a common feature resulting from non-equilibrium conditions during solidification. The aim of this work is to predict the occurrence and severity of microsegregation in highly alloyed, centrifugally cast high speed steel used for rolls. The prediction was performed using thermodynamic Scheil-Gulliver modelling with Thermo-Calc software. The modelled predictions were then compared with differential scanning calorimetry, X-ray diffraction, light and electron microscopy with energy dispersive spectroscopy, all performed on an as-cast roll shell. Results show that chromium, molybdenum and vanadium have the highest tendency to microsegregation. Vanadium tends to form negative microsegregation, while molybdenum and chromium form positive microsegregation. Scanning electron microscopy revealed the presence of complex eutectic carbides, confirming the Scheil-Gulliver non-equilibrium solidification path via two main successive eutectic reactions.

Authors: Kazeri-Shandiz Shima , Beyramabadi Ali , Morsali Ali
Published: September 2017

Halofuginone is a potential anti-malarial drug, which could exist as three possible tautomers. Herein, using density functional theory (DFT), and handling the solvent effects with the PCM model, the tautomerism of halofuginone was investigated. Intramolecular H-bonds play an important role in the stability of the tautomers. The conformer H1a is the most stable. Noncovalent interactions of the H1a conformer with the armchair (5,5) single-wall carbon nanotubes and ?-Fe2O3 nanoparticles were explored in several manners. The most stable form of them was determined. The intermolecular H-bonds play a substantial role in the energy behavior of the interaction between ?-Fe2O3 nanoparticles and halofuginone.

Authors: Liu Banghai , Jin Chunji , Wan Jiteng , Li Pengfang , Yan Huanxi
Published: September 2017

This study proposes a novel hybrid of artificial neural network (ANN), genetic algorithm (GA), and particle swarm optimization (PSO) to model and optimize the relevant parameters of an electrochemical oxidation (EO) Acid Black 2 process. The back propagation neural network (BPNN) was used as a modelling tool. To avoid over-fitting, GA was applied to improve the generalized capability of BPNN by optimizing the weights. In addition, an optimization model was developed to assess the performance of the EO process, where total organic carbon (TOC) removal, mineralization current efficiency (MCE), and the energy consumption per unit of TOC (ECTOC) were considered. The operation conditions of EO were further optimized via PSO. The validation results indicted the proposed method to be a promising method to estimate the efficiency and to optimize the parameters of the EO process.

Effectiveness of Intranasal Sodium Hyaluronate in Mitigating Adverse Effects of Nasal Continuous Positive Airway Pressure Therapy
Authors: La Mantia Ignazio , Andaloro Claudio
Published: September 2017

Background

Nasal continuous positive airway pressure (CPAP) in moderate-to-severe cases of obstructive sleep apnea can cause nasal discomfort and other undesirable problems.

Objective

The aim of our study was to test the effects of sodium hyaluronate on nasal problems that patients experienced in their daily lives, sleepiness, nasal resistance to airflow, nasal mucociliary clearance, changes in inflammatory markers, and compliance to CPAP in three groups of patients with obstructive sleep apnea syndrome on CPAP therapy.

Methods

A total of 102 patients with a confirmed diagnosis of obstructive sleep apnea syndrome (apnea-hypopnea index [AHI] of ≥10/hour) were randomized into three treatment groups: (1) hyaluronate plus CPAP, (2) saline solution plus CPAP, and (3) CPAP-only groups. Outcome measures were the extent of improvement in the Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) mean scores, sleepiness, nasal resistance to airflow, nasal mucociliary clearance, changes in inflammatory markers, and compliance to CPAP. Significant improvement in each outcome measure was determined by comparing scores at baseline and after 4 weeks for each treatment group.

Results

Significant improvement in the MiniRQLQ overall mean score was observed both in the hyaluronate plus CPAP (p <0.00001) and saline solution plus CPAP groups (p <0.01), although the hyaluronate plus CPAP group had better improvement compared with the saline solution plus CPAP group (0.24 versus 0.12, respectively). An increase in nasal inflammatory markers and saccharin transit test score was observed in all three groups, although it was statistically lower in the hyaluronate plus CPAP group (all p <0.001).

Conclusion

Intranasal hyaluronate showed significant benefits in patients who received CPAP therapy, but future studies over a longer period of time after treatment should be performed to corroborate our findings.
