Significant Enhancement in Built-in Potential and Charge Carrier Collection of Organic Solar Cells using 4-（5-hexylthiophene-2-yl）-2,6-bis（5- trifluoromethyl）thiophen-2-yl）pyridine as a Cathode Buffer Layer

An electron transporting material of TFTTP （4-（5-hexylthiophene-2-yl）-2,6-bis（5-trifluoromethyl）thiophen-2-yl）pyridine） was investigated as a cathode buffer layer to enhance the power efficiency of organic solar cells （OSCs） based on subphthalocyanine and C60. The overall power conversion efficiency was increased by a factor of 1.31 by inserting the TFTTP interfacial layer between the active layer and metallic cathode. The inner mechanism responsible for the performance enhancement of OSCs was systematically studied with the simulation of dark diode behavior and optical field distribution inside the devices as well as the characterization of device photocurrent. The results showed that the TFTTP layer could significantly increase the built-in potential in the devices, leading to the enhanced dissociation of charge transfer excitons. In addition, by using TFTTP as the buffer layer, a better Ohmic contact at C60/metal interface was formed, facilitating more efficient free charge carrier collection.

Aware conflict detection of non-uniform memory access system and prevention for transactional memory

Most transactional memory (TM) research focused on multi-core processors, and others investigated at the clusters, leaving the area of non-uniform memory access (NUMA) system unexplored. The existing TM implementations made significant performance degradation on NUMA system because they ignored the slower remote memory access. To solve this problem, a latency-based conflict detection and a forecasting-based conflict prevention method were proposed. Using these techniques, the NUMA aware TM system was presented. By reducing the remote memory access and the abort rate of transaction, the experiment results show that the NUMA aware strategies present good practical TM performance on NUMA system.

Distribution Regularity of Muzzle Shock-Wave Inside Protective Cover

The injury of gunners caused by muzzle shock-wave has always been a great problem when firing inside the protective cover. The distribution regularity and personnel injury from the muzzle blast-wave were investigated by both test and numerical simulation. Through the inside firing test, the changes of overpressure and noise have been measured at different measuring points in the thin-wall cover structure with different open widths and shallow covering thickness. The distribution regularity of muzzle shock-wave with different firing port widths is calculated by ANSYS/LSDYNA software. The overpressure distribution curves of muzzle shock-wave inside the structure can be obtained by comparing the test results with the numerical results. Then, the influence of open width and shallow covering thickness is proposed to give a reference to the protective design under the condition of the inside firing with the same cannon caliber.

Neuron system shock superimposed response based on catastrophe dynamics

With the rapid development of computer science and artificial intelligence technology, the complexity and intelligence of the neural network models constructed by people have been greatly improved. When the complex neuron system is subjected to the impact of ＂catastrophic＂, its original characteristics may be changed, and the consequences are difficult to predict. Catastrophe dynamics mainly studies the source of the sudden violent change of nature and human society and its evolution. The impact of the system can be divided into endogenous and exogenous shocks. In this article, catastrophe theory is used to study the neuron system. Based on the mean field model of Hurst and Sornette, introducing the weight parameters, mathematical models are constructed to study the response characteristics of the neuron system in face of exogenous shocks, endogenous shocks, and integrated shocks. The time characteristics of the shock response of the neuron system are discussed too, such as the instantaneous and long-term response of the system in face of shocks, the different response forms according to the weight or linear superposition, and the influence of adjusting parameters on the neuron system. The research result shows that the authoritarian coefficient and weight coefficient have a very important influence on the response of neuron system; By adjusting the two coefficients, the purpose of disaster prevention, self-healing protection and response reducing can be well achieved.

Religion Conflicts in Indonesia Problems and Solutions

Religious perspectives which place religion as a source of conflict have initiated various attempts to reinterpret and accordingly find some common ground at a certain level which hopefully may reduce conflicts among religious communities due to the existence of mutual tolerance. At the exoteric level, religions are different, but at the esoteric level, religions are not similar. All religions are viewed as equally valid paths toward God. However, in many ways, the reality shows that the tension among religious communities is closely related to the factors that are beyond the scope of religion. It is important for all religious believers to keep the peace among them. As far as the record of religious conflicts in Indonesia is concerned, it shows three major patterns： conflicts among adherents of different religions, conflicts between one religion with a group accused as heretical, and internal conflicts of the same people of faith with those who have different understanding of the religion. In any point of views, however, such conditions would be so detrimental to the human race in general, and society and the state of Indonesia in particular. This paper examines intensively about the issues and attempts to uncover the nature of the root-causes underlying them.

Eros and Thanatos in the Psychical Process of Paul Morel： Diversity in Paul＇s Psyche

This paper attempts to analyze Paul Morel＇s instinctual drives--in D. H. Lawrence＇s Sons and Lovers （2006}---toward survival, neurotic refusal to accept life, and his will to give life meaning after a fierce and prolonged internal strife--in the light of psychoanalysis. It will explore how his ＂Id＂ strives to bring about the satisfaction of instinctual needs on the basis of the pleasure principle driving him to seek pleasure. His ＂libido＂--psychic energy, emanating from the id, especially the sexual urge--has empowered his ＂Eros＂ or life instinct. It will also explore how ＂Thanatos＂ or death instinct, in contrast, has yearned for an almost lifeless state and curbed entering into human relationships as experienced in his last rejection of Miriam after his mother＇s death leaving a great trauma on Paul who has been on the verse of extinction as a result. Therefore, Eros and Thanatos, both coincide and conflict within him, are dynamically involved and thus are interacted infusing life not stagnation in Paulin consequence

Japanese Social Mentality and the Change in the Approval Rates of the Abe Administration

From June to July of 2017, the approval rates of the Abe administration fell sharply, in stark contrast to the long-term stability since 2012. The stability of Abe＇ s approval rates originated from the people＇ s negative support for him and their opposition to the Security Laws and other important events as well as the scandals under his administration. The opposition and negative support originated from the people＇s ＂acquired helplessness＂, ＂Abenomics＂, the sharp drop in the opporttmity costs of voting and other conditions. The sudden fall of Abe＇ s approval rates was not due to the change in the aforementioned conditions, rather because of the collapse of his image including personality owing to Abe＇ s perceived arrogance and his estrangement with the people. In the context of the temporary stabilization of approval rates, Abe dissolved the House of Representatives ahead of schedule and held a general election, taking full advantage of the internal strife between the opposition parties, to achieve his goal of ruling until the 2020 Tokyo Olympics. His victory in the recent election does not accurately demonstrate that Abe is completely immune to negative impact, thus he will to use the Korean Peninsula crisis and other issues to demonstrate his ability of safeguarding Japan＇s security, seek reconstruction of his image, and further enhance his approval rate to stabilize his administration.

Computational fluid dynamic simulation of an inter-phasing pulse tube cooler

An inter-phasing pulse tube cooler (IPPTC) consists of two pulse tube units, which are connected to each other at hot ends of the pulse tubes through a needle valve. This paper presents the computational fluid dynamic (CFD) results of an IPPTC using a 2D axis-symmetrical model. General results such as the phase difference between pressure and velocity at cold end and hot end, the temperature profiles along the wall, the available lowest temperature as well as its oscillations and the coefficient of performance (COP) for IPPTC are presented. The formation of DC flow and its effects on the performance of the cooler are investigated and analyzed in detail. Turbulence, which is partially responsible for the poor overall performance of a single orifice pulse tube cooler (OPTC), is found to be much reduced in IPPTC and its performance is improved significantly compared with the single OPTC.

The Narrative Perspectives Manifested in AI-Kharrat＇s Novels

This study deals with two novels of Eduar AI-Kharrat： Rama wal-Tinnin （Rama and the Dragon, 1979） and al-Zaman al-Akhar （The Other Time, 1985）. The text in both novels is of the pluralist, polyphonic and modernistic type and the real and the imaginary are juxtaposed. The narrative imitates at its diverse levels the internal conflict, argument, and uncertainty of the protagonist Michael, who finally finds his self-realization in an imaginary time, ＂the other time＂, which is also the title of one of the novels. The present study focuses on the transformation and alternation of the perspectives and the narrative vision through the destruction of the narrator＇s identity and the text itself, the analysis of the narrative shift between the first and third person, the fragmentation of the self, the ambiguity of the signs, the severity of the crisis, and the psychological conflict at its diverse levels and multiplicities. Toward this plurality and shift, it is necessary to systematically depend upon what the theories of Bakhtin and Genette have to offer in order to cover the narrative levels and multiple voices prevailing in the texts.

DCFl-Checker： Checking Kernel Dynamic Control Flow Integrity with Performance Monitoring Counter

It is a challenge to verify integrity of dynamic control flows due to their dynamic and volatile nature. To meet the challenge, existing solutions usually implant an ＂attachment＂ in each control transfer. However, the attachment introduces additional cost except performance penalty. For example, the attachment must be unique or restrictedly modified. In this paper, we propose a novel approach to detect integrity of dynamic control flows by counting executed branch instructions without involving any attachment. Our solution is based on the following observation. If a control flow is compromised, the number of executed branch instructions will be abnormally increased. The cause is that intruders usually hijack control flows for malicious execution which absolutely introduces additional branch instructions. Inspired by the above observation, in this paper, we devise a novel system named DCFI- Checker, which detect integrity corruption of dynamic control flows with the support of Performance Monitoring Counter （PMC）. We have developed a proof-of-concept prototype system of DCFI-Checker on Linux fedora 5. Our experiments with existing kemel rootkits and buffer overflow attack show that DCFI- Checker is effective to detect compromised dynamic control transfer, and performance evaluations indicate that performance penaltyinduced by DCFI-Checker is acceptable.

Resolving Conflicts Within Multicultural Teams in Industrial Enterprises

The aim of this paper is to highlight the issue of resolving conflicts within multicultural teams in industrial enterprises. The authors build upon the concept of multiculturalism which seeks for possible ways to enable different cultures to coexist and the means of communication between them. The authors base the study on the assumption that extensively developed intercultural relationships lead to mutual understanding between people and consequently to less interpersonal conflicts. In the introduction part, the authors explain the importance of increased attention and interest in the area of multiculturalism. Industrial enterprises nowadays are increasingly aware of this issue as they become more open to different cultures and they are confronted with intensive international migration and previously isolated societies become more pluralistic. As a result of these processes, individuals are more frequently in contact with members of different cultures. ＂Think globally, act locally＂ has become a slogan for our society. This way of thinking and acting was transferred to almost all areas of life （economic, political, and educational） and it is applied in the context of schools, societies, and enterprises as well. The ability to understand and accept cultural diversity is becoming essential in the ordinary working environment. It helps to create connections between emotional perception and rational acceptance. In practice, the offer of training seminars about intercultural differences is widespread. Enterprises supporting the knowledge improvement of their own employees have understood that a friendly working environment leads to increased motivation, consequently reflected in their performance. The training focused on skills development in this area can help to reduce interpersonal misunderstandings, bring new ways of conflict resolution and harmony in the workplace and thereby also increase productivity. The authors focus on the ＂outdoor method＂ as an actual phenomenon, which is used in teaching the topic of tolerance towards cultural diversity. They describe the individual stages of this method and introduce a modified version of Tuson＇s model as an effective tool for conflict resolution in the workplace. The tools introduced in this paper, place particular emphasis on actions to prevent conflicts in the workplace. This paper builds upon the theory of knowledge processing and its role as a theoretical basis for knowledge development in the area of multiculturalism. Furthermore, it teaches us to be tolerant towards others, their habits, culture, and history ＂Strangers＂ can be a source of experience for us and they can enrich our personal lives. Discussion of the issues surrounding multiculturalism and also the identification of sustainable key performance parameters within multicultural work environments can contribute to more effective conflict resolution in the workplace and promote awareness towards the tolerant coexistence and social cohesion

Memory Safety Based on Probabilistic Memory Allocation

Some unsafe languages,like C and C++,let programmers maximize performance but are vulnerable to memory errors which can lead to program crashes and unpredictable behavior.Aiming to solve the problem,traditional memory allocating strategy is improved and a new probabilistic memory allocation technology is presented.By combining random memory allocating algorithm and virtual memory,memory errors are avoided in all probability during software executing.By replacing default memory allocator to manage allocation of heap memory,buffer overflows and dangling pointers are prevented.Experiments show it is better than Diehard of the following aspects:memory errors prevention,performance in memory allocation set and ability of controlling working set.So probabilistic memory allocation is a valid memory errors prevention technology and it can tolerate memory errors and provide probabilistic memory safety effectively.

A Practical Online Approach to Protecting Kernel Heap Buffers in Kernel Modules

Heap overflow attack is one of the major memory corruption attacks that have become prevalent for decades. To defeat this attack,many protection methods are proposed in recent years. However,most of these existing methods focus on user-level heap overflow detection. Only a few methods are proposed for kernel heap protection. Moreover,all these kernel protection methods need modifying the existing OS kernel so that they may not be adopted in practice. To address this problem,we propose a lightweight virtualization-based solution that can protect the kernel heap buffers allocated for the target kernel modules. The key idea of our approach is to combine the static binary analysis and virtualization technology to trap a memory allocation operation of the target kernel module,and then add one secure canary word to the end of the allocated buffer. After that,a monitor process is launched to check the integrity of the canaries. The evaluations show that our system can detect kernel heap overflow attacks effectively with minimal performance cost.

THRUST NAPPE STRUTRUE IN THE JINGGANG MOUNTAIN: CHARACTERISTICS AND SIGNIFICANCE FOR PROSPECTION OF ORE DEPOSITS

Nappe structure, as was first discovered by the authors during the regional geological survey at the scale of 1:50,000 in The Jinggang Mountain, is mainly comprised of a series of NNE-NE-striking thrust fault zones and thrust sheets among them. Sinian, Cambrian, Ordovician, Devonian, Carboniferous,Triassic, Jurassic and Cretaceous strata are involved in the thrust nappe system. The nappe structure is of the type of duplex structures formed as a result of the earlier stage migration from SE to NW and late stage migration from E to W of sedimentary cover or basement strata. Formation of the nappe structure in the studied area involves two main epochs: Early Yanshanian and Late Yanshanian to Early Himalayan. The mineral deposits and the buried coalfields in the area, especially the latter, are extensively controlled by the nappe structure.

Shock Train and Pseudo-shock Phenomena in Supersonic Internal Flows

When a normal shock wave interacts with a boundary layer along a wall surface in supersonic internal flows and the shock is strong enough to separate the boundary layer, the shock is bifurcated and a series of shocks called “shock train” is formed. The flow is decelerated from supersonic to subsonic through the whole interaction region that is referred to as “pseudo-shock”. In the present paper some characteristics of the shock train and pseudo-shock and some examples of the pseudo-shocks in some flow devices are described.
