¿Un Marx sin economía? Crítica de la teoría del valor como 'análisis de las formas'
Authors: Nieto Ferrandez Maxi
Published: December 2020

El artículo critica la interpretación de la teoría del valor de Marx como mero “análisis de las formas” que propone Clara Ramas en Fetiche y Mistificación Capitalistas. Argumentamos que se trata de una interpretación reduccionista que no se hace cargo de las exigencias analíticas que impone el propio objeto de estudio que define Marx: la necesidad de articular la dimensión cualitativa y cuantitativa de la teoría del valor. Y señalamos las implicaciones tanto teóricas (imposibilidad de dar cuenta de la dinámica económica capitalista) como políticas (sustitución del comunismo por el populismo).

Effect of attitudes, subjective norms and behavioral controls on the intention and corrupt behavior in public procurement: Fraud triangle and the planned behavior in management accounting
Authors: Zulaikha Zulaikha , Hadiprajitno Paulus T. Basuki , Rohman Abdul , Handayani Rr. Sri
Published: December 2020

This study explores the values that develop in society which are social constructs that are thought to be related to attitudes, norms, and controlling individual behavior in society and in turn can foster intentions and behavior to corrupt. This research was conducted empirically by involving 265 respondents from accountants, stakeholders, civil servants and inspectors in Central Java, Indonesia who were analyzed by Structural Equation Modeling (SEM) with AMOS analysis tools. The theoretical test results confirm the fraud triangle and the theory of planned behavior to study the opportunity and financial process factors and the rationalization factor which emphasizes the moral psychological aspects. In practical terms, these findings underline the need for tiered supervision in the implementation of goods and services procurement projects in the public sector, improve the quality of reporting and accounting systems, and improve individual integrity to carry out work. Also, it is necessary to increase the remuneration of employees and provide competitive pricing for the private sector involved in procurement projects to minimize intentions for corruption and corrupt behavior by improving the quality of life of the individuals involved in supervision, auditing and reporting.
The choice of capital structure: A study on energy industry in a developing country
Authors: Nga Nguyen Thi Viet , Long Giang Ngoc
Published: December 2020

The choice of capital structure has greatly contributed to the success of the firms in general and energy in particular. This study uses a sample data set of 250 energy firms over the period 2010-2019, and by using generalized least square (GLS) method to perform a survey. The main factors in this study include profitability, firm age, state shareholding and depreciation tax shield, etc. The study found that except firm growth, all factors including firm performance, age of firm, size of firm, asset structure, short-term solvency, and depreciation have significantly affected firm’s capital structure choice in the case of energy industry in a developing country. Furthermore, a positive effect was also found for size of firm and asset structure while a negative effect was detected for other factors such as firm performance, asset structure, firm age, short-term solvency, and depreciation. Through this research, we also conclude that the theory of pecking order, and the theory of representative cost are known as the basis for financial managers to build sound capital structures for businesses.

This study analyses the factors that users of consumer-to-consumer (C2C) commerce value as direct influences in the intention to use and the acceptance of a marketplace. An empirical model is formulated, which integrates three variables that evaluate trust and, in turn, other variables that influence C2C intention and purchases, taking a sample of 686 surveys gathered using the Internet in Colombia. The results show that trust is a fundamental factor in this type of electronic commerce in Colombia, given that C2C users seek intermediation pages with third-party recognition (TPR) and high web quality; similarly, key variables in the adoption of this type of commercial platform include finding low prices and social influence. The perception of trust in this type of electronic commerce is a broader concept that requires the analysis of psychosocial factors. For companies that manage marketplaces, this study allows them to focus on key actions and tools in their websites. This study allows one to get to know the users of this transactional system, specifically for the Latin American region, highlighting the variables that they most consider when engaging in direct commerce between people. The results show that C2C requires marketplaces that guarantee the necessary conditions for a purchase/sale transaction with trust and quality.

This article tests different theories, as proposed by the author (Abadia 2016) and by reputed researchers such as Porter (1985), Christensen (1997) and Tellis (2006), on why some technology-related startups are successful in fast-changing environments, while well-established firms are not. To this end, the author conducted (i) four different database statistical analyses – data aggregation, segmentation, time comparison, and linear regression/correlation – on the financial statements of a large sample population of technology-related startups, in two countries, the United States of America (USA) and Spain, and (ii) nine cases studies of particularly successful technology-related startups in four countries, the USA, Spain, China and Japan. The combination of the statistical and case studies concludes that (1) visionary leadership is a necessary condition for ‘disruptive success’, (2) disruptive or, at least, revolutionary innovation is a necessary condition for disruptive success, (3) location in specialized clusters is a critical factor in determining the rate and level of success of technology-related firms. On the other hand, the study concluded that entrepreneurs and executives should seek and exploit these three competitive elements in the stages of introduction and growth. However, in the case of the maturity stage, the emphasis should be directed towards other elements that are less elitist and volatile.

Worldwide it is estimated that more than 85% of the main companies used external logistics services, with growth rates of this services market projected between 18 and 22 percent per year. This trend has generated a growing interest in supply chain researchers to propose different approaches for the selection and evaluation of the performance of third party logistics (3PL). This article proposes a systematic review analyzing a sample of articles published in indexed journals in order to identify the main contributions on this topic. This study shows the evaluation and selection of a 3PL is a critical and complex decision, due to the existence of several criteria of imprecise and subjective basis. As a result, methodological characteristics, approaches used, models applied, attributes of the magazines, and industries that use external logistics providers are presented. Cost, information technology implemented by logistics providers, and the effectiveness of shipments and deliveries on time, are the most valued criteria by companies for the evaluation and selection of 3PL. The results of this study provide support to researchers, as a reference that allows identifying some possibilities for future research in the field of providers that offer external logistics services, promoting competitiveness in the supply chain.

The link between the enterprise and the university in Morocco is positioned within the framework of what is commonly known as the “University’s Third-Mission”. This relationship is primarily concerned with continued education, consultancy, collaborative research and development (R&D) and technology transfer from the university to the enterprise. This third mission has been promoted by the university through the establishment of specialized structures such as university enterprise interfaces, incubators and technological information centres for invention patents. Also, several strategies and programs of incentives for innovation have been promoted by the public authorities to create a national system of innovation in Morocco. However, all these efforts failed to unleash and activate the potential of Moroccan universities. In this work, we will propose an effective and efficient institutional Technology Transfer (TT) policy backed up by a complete repository related to the establishing of the University Technology Transfer Office (UTTO). This proposal complements the work done in a previous paper, which assesses the different policies and programs within Moroccan universities, related to TT activities, and proposes a remodelling of the value chain of the process of technology transfer in the universities.

A life settlement is a financial transaction by which an existing life insurance policy is sold to an investor for a greater price than its cash surrender value. In this way, the investor undertakes to pay, if any, the outstanding premiums and has the right to receive the death benefit when the insured dies. This work carries out a descriptive analysis of this type of transaction and a study of its main quantitative aspects. Thus, among other aspects, an overview of the product is offered and its main agents, the nature of the parameters involved in its value and the risks related to it are described. In regards to the quantitative point of view, a new way of analysing the sensitivity of the price of a life settlement to changes in the insured’s life expectancy is introduced. Indeed, we extend the duration and convexity indicators of Stone and Zissu (2008), which use a deterministic approach, to the analytical framework provided by the probabilistic valuation method. Then, we propose to measure the sensitivity of this product to changes in the insured’s mortality multiplier, and not in their life expectancy. The paper also describes the applicability of the new measures for risk management purposes.

Published: December 2020

Pesquisas que abordam empresas familiares e não familiares possuem diferentes enfoques, porém poucas são as que estudam a divulgação das informações contábeis, sob a perspectiva de legislação e informações voluntárias. Dito isso, o presente estudo objetivou verificar as diferenças no conteúdo do Relatório da Administração de empresas familiares e empresas não familiares no segmento edificações listadas na Bolsa Balcão Brasil (B3). A amostra do estudo compreendeu 18 empresas familiares e não familiares listadas no segmento de edificações da B3. O período de análise constituiu o ano de 2016 pela relevância do segmento no mercado de capitais. Para análise dos dados foi realizada pesquisa exploratória, com abordagem predominantemente qualitativa, mas que também se utilizou da abordagem quantitativa. Os resultados demonstraram que as médias finais entre as empresas familiares e não familiares não são representativas, assim, não se pode afirmar que as empresas familiares estão utilizando mais os itens destacados como recomendações do Parecer de Orientação n° 15/87 da CVM que rege quanto a divulgação adequada do Relatório da Administração, comparando-se a empresas não familiares, mas em comum, que todas as empresas possuem dificuldades em atender tais recomendações. Este estudo contribuiu para análise da observância da utilização do Parecer em organizações de diferentes tipos, e que em média, ambos tipos não se utilizam dos critérios sugeridos como divulgação pelo Parecer.
Japanese Colonial Land Survey Project and Korean Economic Take-off
Authors: Han Zonghie
Published: December 2020

The mystery of the newly industrialized countries (NICs)s success, including Korea’s take-off, can be addressed by using the concept of a property representation system, as initiated by de Soto (2000). This property representation system, which has been further described as the mystery of capital formation, was supposedly established in Korea during the Japanese colonialization of 1910-1945. The Korean industrialization in this period has been well described by the ‘developmental state’ approach, but the property representation system can reveal the key role of property rights as an institution in the economic take-off, focusing on its incentive function.

Developing countries face environmental degradation crisis due to the consumption of nonrenewable energy for economic development induces ecological destruction. However, the consequences of environmental deterioration can no longer be overlooked. Using data from 1990 from 2018, this study scrutinized the long-run equilibrium along with the trend among consumption of renewable energy, carbon dioxide emissions, Population, and economic growth in Bangladesh. This study reveals the significant cointegration of renewable energy with controlled variables using the ARDL bound test. Also, ECM with ARDL unrestricted version enables us to decide the speed of adjustment is 27.647% addressed for short-run elasticity in the long run. Stability and further diagnostic tests are performed for model post estimation and validation. Also, it needs further steps from the government side to promote renewable energy that boosts economic development.
Den historiske dimensjon i KRLE-faget
Authors: Rasmussen Tarald
Published: December 2020

Artikkelen ser nærmere på den nye læreplanen for KRLE-faget med utgangspunkt i spørsmålet om hvordan en historisk dimensjon er ivaretatt. Planens første «Kjerneelement» lanserer en globalt orientert religionsforståelse som – trass i pretensjonen om å angi en «kjerne» – er videre og mer altomfattende formulert enn i noen tidligere læreplan for faget. Denne åpne bestemmelsen av hva man skal arbeide med, går hånd i hånd med en svekking av et historisk perspektiv som siden KRL-faget ble lansert i 1997, har spilt en viktig rolle i læreplanene. Et hovedspørsmål i artikkelen er om en slik dreining i forståelsesform bidrar til å styrke eller til å svekke en dypere forståelse av religion i skolen. Kan en slik dypere forståelse oppnås uten historisk arbeid med spesifikke religiøse tradisjoner?

Cash Flows Indicators in the Prediction of Financial Distress
Authors: Karas Michal , Režňáková Mária
Published: December 2020

We argue that the conventional approach to bankruptcy modelling, which relies on accrual-based ratios, is vulnerable to the earnings management of a company threatened by insolvency. This fact may pose significant limits on the possibilities of distress prediction. Business distress is defined as cashflow insufficiency, and cashflow indicators are less vulnerable to earnings management. For these reasons we assume that cashflow ratios are theoretically more suitable for predicting distress. In our research we analysed the usefulness of cashflow-based ratios as potential predictors of bankruptcy. During the research, the cashflow-based ratios take the form of many variants of operating, financial, investment and free cashflow into a firm in combination with total assets, sales, liabilities and other indicators. The research was carried out on a sample of 4,350 Czech manufacturing SMEs operating during the period between 2013 and 2018. We employ the previously published approach of hybrid modelling to create the prediction model, though we propose a modification for the purposes of this paper. The modified hybrid model employs Classification and Regression Trees and Logistic Regression, while we use the Principal Component Analysis method to deal with the problem of multicollinearity. The results showed that operating cashflow ratios play a significant role in financial distress, especially when combined with short-term debts.
Friedenslogik – Leistungsvermögen, Geltungsanspruch, Anfragen*
Authors: Jaberg Sabine
Published: December 2020

The logic of peace approach possesses specific potentials: It distills a few essentials of peace, makes peace more fluid, and defines peace and security in a special manner. Maybe it also provides a base for a deep reflexive but always incomplete theory of peace. The claimed validity can be described as a conditioned universality. Points of criticism can be refuted: The discrimination between peace and security is still necessary. Safety remains an important value, but it should be achieved by the logic of peace instead by the logic of security. Obviously, a powerful and ‘hell-bent’ aggressor is an excessive demand. But this is true for all logics. Instead of giving up the approach, it is better to make contextual adjustments and conduct deeper elaboration.
Ambivalenzen im Konzept „Friedenslogik“
Authors: Ebeling Klaus
Published: December 2020

Starting with a reflection on the theory of subjectivity by Dieter Henrich, especially his idea of human life as a process of balancing contrary interests and views on life, the author aims at developing a concept of ethical pragmatism. It is centred on the dynamic relation between acceptance and exclusion. With reference to the discussion on securitization of social and political affairs, the concept of peace and security as promoted by Sabine Jaberg and others, the author proposes to modify the thinking “from opposition to complementarity”. In the concluding section, the idea of complementarity is illustrated by the example of the dogmatism in disputes on deterrence with nuclear weapons.
Friedenslogik als konstruktive Angstbewältigung – eine Neuvermessung in Anschluss an die Tiefenpsychologie Fritz Riemanns
Authors: Luithlen Susanne
Published: December 2020

The four basic fears described by Fritz Riemann are a useful frame to revisit the logic of peace and the logic of security with regard to their positioning to each other. This approach stipulates that instead of the logic of peace and the logic of security being opposite to each other a third logic - the logic of capitulation - needs to be introduced to be the opposite. It shows that the logic of peace holds a middle position, integrating the extremes dynamically and flexibly to different situations without developing a fixed inclination to just one.

Role of Copy Number Variations in ADHD
Authors: Krgović Danijela
Published: December 2020

Copy number variations (CNV) have an important role in etiology of neurodevelopmental disorders (NDD). Among them, individuals with attention-deficit and hyperactivity disorders (ADHD) have 1.33 times higher overall rate of CNVs larger than 100 kb compared to healthy controls. These CNVs are often shared with other NDDs and neuropsychiatric disorders such as schizophrenia (SCZ) and autism spectrum disorder (ASD), although duplications of 15q13.3 and 16p13.11 have been found enriched in ADHD cohorts. CNVs provide new opportunities for studying and management of psychiatric disorders including ADHD. Therefore this chapter provides a brief overview of the literature on this topic and presents the benefits of CNV genetic diagnostics in ADHD patients.

Challenges and Opportunities in Marginal Zone Lymphoma: Implications of Biology on Treatment
Authors: Smith Stephen D.
Published: December 2020

Although sharing some common features in terms of etiology and even clinical presentation, marginal zone lymphoma is a heterogeneous group of diseases, with subtypes that can present in unexpected ways, especially with regard to autoimmune disease. There’s a proven role of antimicrobial therapy for both Helicobacter pylori and hepatitis C virus, and 10-year overall survival is high. Because this disease requires continuous treatment, therapy should be properly sequenced, with consideration given to patient comorbidities and age. Finally, B-cell receptor signaling inhibitors and immunomodulatory agents can provide responses and disease control.
Peripheral T-Cell Lymphomas–Not Otherwise Specified: A Shrinking Entity?
Authors: Horwitz Steven M.
Published: December 2020

Peripheral T-cell lymphomas–not otherwise specified (PTCL-NOS) is a broad category of biologically and clinically heterogeneous diseases, which likely does not have a single treatment paradigm. Understanding of subtype-specific approaches is leading to more individualized therapy. There are also therapeutic vulnerabilities to target, such as CD30, JAK/STAT pathway, and epigenetic modifiers, that may cross different histologic subtypes. As new therapies evolve, however, it is important to understand in which situations current standard treatments work, because some of these treatments, such as combination chemotherapy, are potentially curative for a subset of patients. For certain populations, adding to these chemotherapy backbones will produce the best results. For other populations, entirely new approaches may be appropriate. Future treatment advances will, in part, be made by enriching populations based on their likelihood of response to specific therapies and utilizing biomarker-driven or biomarker-informed strategies.
Evolving Concepts in the Diagnosis and Staging of Multiple Myeloma
Authors: Hillengass Jens
Published: December 2020

Until recently, treatment for multiple myeloma was only initiated in symptomatic disease. Greater understanding of the underlying biology and the development of new biomarkers, however, has led to changes in diagnosis, and with the help of improved imaging techniques, clinicians are increasingly identifying patients with early myeloma who may benefit from treatment. One major development in diagnostic imaging is the replacement of radiography with CT. PET/CT imaging is also useful for treatment response assessment, because the disappearance of focal lesions is an important prognostic factor. Finally, the Revised International Staging System for multiple myeloma has incorporated additional prognostic markers of aggressive disease, and risk-adapted treatment has been shown to improve survival.

L’eau courante dans les logements et le passage des latrines aux W.-C. modifient les conditions de vie. Cette étude en précise la chronologie à Montréal. L’aqueduc mis en service fin 1856 dessert neuf ménages sur dix en 1871, mais peine à rejoindre les autres avant la fin du siècle. Quant aux toilettes à eau, on note une conversion massive de 1887 à 1895 dans la majorité des ménages ouvriers de Montréal, conversion qui se terminera grâce à un règlement municipal adopté en 1901.
L’affaire de la Mary Fortune. Les traités de Saint-Germain de 1632 et la souveraineté sur le Canada
Authors: De Waele1 Michel
Published: December 2020

Le 29 mars 1632, la France et l’Angleterre signent deux traités qui mettent officiellement fin à la guerre qui les avait opposées de 1627 à 1629. Les historiens considèrent généralement que l’un de ces traités remettait officiellement la France en possession du Canada et de l’Acadie. Or, les Anglais ne l’entendaient pas ainsi et continueront à revendiquer la souveraineté sur l’ensemble de ce territoire, hormis les places précises cédées à la France en mars 1632 : Québec, Port-Royal et le Cap-Breton. L’affaire de la Mary Fortune, navire anglais arraisonné dans la baie de Tadoussac en 1634, expose au grand jour ces divergences d’interprétation.
Acceso al empleo de las personas con discapacidad: situación en el empleo en las personas con enfermedad mental
Authors: Salinas Tomás Manuel Francisco , Marhuenda Fluixá Fernando
Published: December 2020

Las personas con enfermedad mental encuentran mayores dificultades en el acceso al empleo que otras personas que también forman parte del colectivo de personas con discapacidad.Los datos estadísticos que hablan del empleo de personas con discapacidad suelen aglutinar bajo el término discapacidad psíquica tanto a personas con enfermedad mental como a personas con discapacidad intelectual. Dicha agrupación da lugar a equívocos, puesto que se trata de discapacidades bien diferenciadas y cuyo tratamiento requiere un abordaje específico tanto en apoyos como en medidas específicas de inserción.Un estudio de los datos estadísticos de las diferentes modalidades de inclusión laboral reguladas en la legislación nos lleva a la conclusión de que es necesario un cambio en el sistema de recogida de datos y su tratamiento para poder diferenciar la enfermedad mental del resto y así poder elaborar medidas de inclusión diferenciadas y por tanto de mayor eficacia.

Published: December 2020

El presente estudio aborda sociedades cooperativas cuyo objetivo es la inserción social y laboral de los grupos clasificados como vulnerables en la legislación brasileña. Con ese reto, el estudio contextualiza las políticas públicas existentes en el país con respecto a los grupos vulnerables y las formas de inserción social y laboral, centrándose en medidas normativas e institucionales que fomentan la participación de estos grupos en las empresas sociales. Teniendo en cuenta la dificultad de datos y de investigación cuantitativa sobre las empresas dedicadas al tema, este trabajo trae ejemplos concretos de acciones y agentes, entre ellos cooperativas, que han estado trabajando en la inserción de grupos vulnerables, centrándose en drogadictos y personas con discapacidad. Para ilustrar el escenario problemático observado en Brasil, también se mencionaron ejemplos de cooperativas que actualmente están inactivas, principalmente debido al desafío de la autosostenibilidad de su estructura organizativa.

En el presente trabajo se analiza desde un punto de vista jurídico, el fenómeno del cooperativismo de iniciativa social como herramienta al servicio de la inserción laboral de colectivos en riesgos de exclusión social o colectivos con especiales dificultades para el acceso al empleo, así como el papel que desempeñan los centros especiales de empleo de iniciativa social como coadyuvantes de las cooperativas de iniciativa social (de trabajo asociado o de consumidores) en la consecución de aquel fin. Desde distintas instituciones y organizaciones en esta materia y desde hace ya algún tiempo, se apuesta por potenciar el empleo ordinario como mejor instrumento de integración social para lo cual son necesarios mecanismos eficaces para facilitar el tránsito desde el empleo protegido al ordinario.
La inclusión socio-laboral de los grupos vulnerables. Colectivos y formas de inclusión a través del trabajo
Authors: Bengoetxea Alkorta Aitor
Published: December 2020

La noción de los grupos vulnerables se encuentra cada vez más extendida en la literatura sociológica, y también en la jurídica. Pero no hay un concepto jurídico-positivo sobre los mismos, ni una lista que los enumere con carácter exhaustivo. Se propone analizar el origen y contornos de esa noción, esbozando un concepto jurídico. En materia de acceso al empleo, la ley de empleo los denomina colectivos prioritarios. Estudiaremos cuáles son, por qué se les considera colectivo prioritario, en función de las peculiaridades de cada uno de ellos, y qué medidas de acción positiva se les aplican,  artiendo de su desventaja, para procurar ayudarles en su esfuerzo hacia la consecución de un empleo.
Sobre el órgano judicial competente para resolver la casación frente a normas de derecho civil autonómico. Comentario al Auto 8857/2018, de 5 de septiembre, de la Sala de lo Civil del Tribunal Supremo

El Auto 8857/2018, de 5 de septiembre, de la Sala de lo Civil del Tribunal Supremo determina la competencia respecto de la resolución de un recurso de casación planteado por una cooperativa gallega frente a una sentencia en apelación de la Audiencia Provincial de A Coruña. El Auto, que reitera la posición de otro Auto de marzo de 2015, supone una modificación en la línea jurisprudencial de la Sala Primera del Tribunal Supremo al considerar que la competencia, por tratarse de derecho civil autonómico –no derecho foral- corresponde al Tribunal Supremo y no al Tribunal Superior de Justicia de Galicia, como se había venido considerando anteriormente.

Authors: Zha Xin-Wei  ,   西安邮电学院应用数学与应用物理系，西安 710061
Published: December 2020

In accordance with the principle of superposition，for the teleportation of an arbitrary three-particle state via three pair nonmaximally entangled particles, the system state of particles can be expanded by Bell bases and transformation operator, and the teleportation can be realized only by performing a inverse transformation. The relation of transformation operators with unitary operation is discussed. The necessary condition to realize the teleportation is that the transformation operators have inverse operators.

The two-level atom is described by Pauli sign and the environment is described by infinite harmonic particle thermal reservoir. We have studied the problem of fidelity of quantum states of two-level atoms located in strongly thermal radiation field. The two-level atoms' reducible density rectangular array is obtained. We discuss the properties of fidelity. It is shown that for the two two-level atoms initially situated in different coherent superposition states, quantum information may partly lose fidelity or may not lose fidelity during evolution in transmission process.

A general dynamical model for disaster spreading is established in this paper, aiming at some common characteristics of key lifeline systems such as power supply network, water supply network, gas supply network, traffic network and communications network, etc. This model considers self-healing function, disaster spreading mechanism and internal stochastic noise of nodes. And the effects of three key parameters,namely the self-healing factor, duration delay factor and noise intensity, on recovery rate and number of damaged nodes for three different network topologies, i.e. Erdos-Renyi network, scale-free network and small world network are investigated. Simulation results are consistent with the characteristics of these true lifeline systems, showing that the presented model can effectively model disaster evolving dynamics for lifeline systems.
Stochastic resonance in optical bistable system

Published: December 2020

The stochastic resonance (SR) in an optical bistable system under the simultaneous action of multiplicative and additive noises and periodic signal is studied using the adiabatic approximation theory. The signal-to-noise ratio(SNR)is a non-monotonic function of intensity of additive noise, in which the SR phenomenon appears. The SNR decreased with the intensity of multiplicative noise, and SR phenomenon does not appear. So the effects of additive and multiplicative noise on the output SNR are different.

Published: December 2020

In this paper, by choosing an ansatz consistent with the asymptotic forms of the correlation and response function, the self-consistent mode-coupling theory is generalized to the analysis of the dynamic scaling of the nonlocal Sun-Guo-Grant equation and the values of the dynamic exponent depending on nonlocal parameter ρ are calculated numerically for the substrate dimension d=1, 2 dimensions，respectively. The results obtained are compared with that of dynamic renormalization-group theory and scaling analysis.

Based on the concept of dinuclear system, considering the strong competition between fusion and quasiffision processes, by solving the master equation numerically to calculate the fusion probability of superheavy nuclei, we have estimated the excitation functions for the reactions 50Ti,58Fe+208Pb,209Bi, and the experimental data are basically reproduced. For different incident energies and different angular momentum, the effects on fusion and survival probability and the contribution to evaporation residue cross section have been given. These results help to further understand the mechanism for synthesizing superheavy nuclei.

On the basis of the improved averaged atomic model, the distribution of the free electrons is dealt with by the partial-wave method to improve the precision of determination of the energy level, electron populations and atomic inner energy.　The obtained results of atomic energy for ground state are in rather good agreement with that of Hartree-Fock method. As samples, the total electron energies of W, Au, Rn and Am are calculated respectively.

Spatially resolved reflectance close to the source is dependent on high-order optical parameters of the media. In order to investigate the influence of high-order parameters on the diffuse reflectance, we define sensitivities of the spatially-resolved diffuse reflectance to the second- and third-order optical parameters. The sensitivity denotes the relative change of diffuse reflectance due to a change in the optical parameter. Expressions of the sensitivities are derived from P3 approximation theory, and numerical analyses are performed. We show that the sensitivity changes with source-detector separation and reaches a maximum in the region between one transport mean free path and two transport mean free paths, and is positive in the region beyond one transport mean free path. The influence of third-order optical parameter on the diffusing reflectance can be ignored in comparison with the influence of second-order optical parameter.
Multi-mode hopping in Nd:YAG lasers with optical feedback
Authors: Tan Yi-Dong  , Zhang Shu-Lian  ,   清华大学精密测试技术及仪器国家重点实验室，北京 100084
Published: December 2020

The multi-modes hopping in Nd:YAG lasers induced by optical feedback is presented. The threshold gains of different longitudinal modes are modulated by optical feedback. The mode which has the lowest threshold gain can oscillate. During the tuning of the external cavity length, when the threshold gain of the oscillating mode is higher than that of the adjacent mode, mode hopping occurs, and the intensity modulation curve fluctuates correspondingly. The different positions of hopping modes in the gain curve lead to different mode hopping points and intensity modulation curves. The closer to the center frequency, the larger intensity amplitude and the longer oscillating period the mode has. When the frequencies of two hopping modes are symmetric about the center frequency, the intensity amplitudes of them are equal, and their oscillating periods are equal too.

Stimulated Brillouin scattering(SBS) is one of important nonlinear optical phenomena, which is widely used in the areas of phase conjugation, pulse compression and beam combination. In this paper, a single axial and single transverse mode Q switched laser system is used as pump source and SBS is investigated experimentally in small bulk fused silica. Damage free operation is observed with SBS reflectivity up to 60%. The self-Stokes-seeding effect, which has been reported elsewhere, is verified. To improve reflected energy and SBS efficiency, two SBS samples connected in series is configured, but the SBS reflectivity cannot exceed 60% due to surface damage.
