LİBERALİZM VE SOSYALİZMDE BİREY(CİLİĞ)İN ONTOLOJİK ÇIKMAZI
Authors: DUMAN Mehmet Zeki
Published: December 2020

Günümüz toplumlarında siyasal sistemlerin ve ideolojilerin en çok üzerinde durduğu temel kavramlardan birisi de birey ve bireyciliktir. Zira moderniteyle beraber, yasama, yargı ve yürütme gibi toplumun yönetimsel mekanizmalarını oluşturan siyasi sistemler ve dünyayı anlamamıza ve yorumlamamıza imkân veren ideolojiler, toplumun özel bir anlam yüklediği bireyin; ontolojik, politik ve ahlaki açıdan nasıl ele alınması ve tanımlanması gerektiği konusunda önemli tartışmalara girmişlerdir. Bu tartışmaların odağında bireyin yer almasının temel nedeni ise, söz konusu sistem ve ideolojilerin oluşturmak istedikleri rejimlere uyan/uygun bir yurttaş/yoldaş kimliğini yaratmak istemeleridir. Çünkü hem siyasalar hem de ideolojiler, her zaman için ideal bir birey anlayışını ve adil bir düzen tasavvurunu savunmuş ve bu hayalin gerçekleşebilmesi için de işe, öncelikle birey/bireycilikten başlamışlardır. Nitekim kökeni, her ne kadar 17. yüzyıla kadar götürülse de 19. yüzyılın başından itibaren reel ekonomi-politik bir sistem olarak tekamül etmiş ve halen günümüz dünyasında birçok farklı düşünce, değer ve inancı kucaklamayı başarmış olduğu için de bir meta-ideoloji hüviyetini kazanmış olan liberalizmin de, yine aynı yüzyılda sanayi kapitalizminin yarattığı sınıfsal çatışmalara ve aşırılıklara tepkisel bir biçimde karşı çıkmasıyla ve özellikle de işçi sınıfının hayalini süsleyen komünal düzeni savunmasıyla kitlesel/küresel düzeyde bir toplumsal/devrimsel harekete dönüşen sosyalizmin de ana teması ve vurgusu, hep birey ve bireycilik olmuş, ancak her iki ideolojinin referans kaynakları, felsefi dayanakları ve epistemik yaklaşımları aynı olmadığı için birey kavramına yükledikleri anlam ve bireyciliğe biçtikleri misyon da farklı olmuştur. Bu farklılığın hem sosyolojik temelini hem de birey üzerinden kopartılan fırtınanın esas nedenini anlamaya dönük bir çabayı içeren bu makale, söz konusu ideolojiler açısından modern bireyin kimliğinin neliğini sorunsallaştırmaya çalışmaktadır. Makale, aynı zamanda hem bireyi toplumdan soyutlayan ve onu tek başına bir ada olarak gören liberal bakışın, hem de bireyi ana karanın bir parçası olarak gören ve onu topluma kurban eden sosyalist yaklaşımın sorunlu olduğunu iddia etmektedir.
Peripheral Odontogenic Fibromyxoma: A Report of a Unique Case
Authors: Sil Shiladitya
Published: December 2020

Odontogenic myxoma is a benign, locally aggressive neoplasm that is known to have a high recurrence rate. Fibromyxoma is a variant of myxoma with a higher fibrous–myxoid tissue ratio. The peripheral type of odontogenic fibromyxoma still remains a diagnostic challenge, as very few cases are reported in the literature. One such case is reported here. A 54-year-old male patient reported to our OPD with a diffuse, slowly enlarging growth in the lower right side of the jaw without crossing the midline. Orthopantomogram was done that revealed generalized bone loss with cratering at the lesion site. Incisional biopsy was done along with immune histochemical evaluation for diagnosis confirmation. Surgical excision was done. No recurrence has been reported till now. These lesions clinically mimic any benign peripheral neoplasm. Hence, precise diagnosis is imperative before initiation of management protocols. Wide margin excision and rigid follow-up are recommended to minimize the chance of recurrence.

The reconstruction of symbolic space at Colombian-FARC peace process
Authors: Ateş Burç Safiye
Published: December 2020

Although long-armed conflicts between the Colombian government and the FARC        organization have witnessed the occasional peace talks, it could evolve in peace after 2012. The peace process, which was announced to the public in 2016 with an official agreement, was a process consisting of many strategic steps, thus making it mandatory to regulate many areas. One of these areas is the symbolic area. In this study, which discusses the argument that the symbolic space must be regulated and renewed in peace processes, it is discussed how the peace of Colombia is read through symbolism and how the conflictual sides transform and reframe the symbolic space. As a result, it has been observed that the efforts of the parties (in this peace process) in transforming the symbolic area have a very important place for the lasting peace, so the symbols are not only superficial units put into the secondary plan, but on the contrary, they have been used actively and effectively from the beginning of the process.

Tin Enrichment in Magmatic-Hydrothermal Environments Associated with Cassiterite Mineralization at Ardlethan, Eastern Australia: Insights from Rb-Sr and Sm-Nd Isotope Compositions in Tourmaline
Authors: Carr Patrick , Norman Marc D. , Bennett Vickie C. , Blevin Phillip L.
Published: December 2020

Primary cassiterite mineralization is often associated with highly evolved granites, but the magmatic and hydrothermal processes that produce these deposits are often difficult to decipher. In this study, we employed the chemical and Sr-Nd isotope compositions of tourmaline to monitor processes of Sn enrichment in the magmatic and hydrothermal stages of the Ardlethan granite (Australia) and its associated Sn deposits.

Initial 87Sr/86Sr (0.710–0.717) and ɛNd (–5.0 to −1.0) values of late magmatic tourmalines indicate derivation of the Ardlethan granite via an assimilation-fractional crystallization (AFC) process in which incorporation of Ordovician sediment into an I-type granitic parental magma produced an enrichment of Sn at least 30 times over that of the assumed mafic-dominated igneous source of the granite.

The rare earth element and Sn concentrations of tourmaline in the greisen deposits together with δ18O of coprecipitated quartz indicate that exsolution of a late-stage, Cl-rich fluid from the Ardlethan granite led to cassiterite mineralization in these deposits. In contrast the Fe/(Fe + Mg) and initial εNd (–9.2 to −12.9) compositions of tourmaline that coprecipitated with cassiterite in the large breccia pipes adjacent to the Ardlethan granite suggest that granite-derived fluids scavenged Sn by chemical leaching of an older S-type granite that hosts the pipes.

This study shows that tourmaline can act as a robust monitor of key geologic processes in complex and dynamic magmatic-hydrothermal Sn systems and that its 87Sr/86Sr and ɛNd isotope compositions are especially useful for constraining the nature of magmatic and hydrothermal sources that contributed to these deposits.
Carbonate Replacement as the Principal Ore Formation Process in the Proterozoic McArthur River (HYC) Sediment-Hosted Zn-Pb Deposit, Australia

Published: December 2020

The McArthur River (HYC) Zn-Pb-Ag deposit in the Carpentaria Zn belt, northern Australia, is one of the world’s largest and most studied sediment-hosted base metal deposits, owing to its lack of deformation and preservation of sedimentary and ore textures. However, the ore formation process (syngenetic vs. epigenetic) is still a subject of controversy. In this paper we focus on key characteristics of the HYC deposit that remain unexplained: preservation of sedimentary carbonate (dolomite) and its association with Zn, and the role of thallium (Tl) and manganese (Mn) distribution in the orebody.

Our findings demonstrate a sequence of events during ore formation: Tl is hosted almost exclusively within euhedral pyritic overgrowths around early diagenetic pyrite; sphalerite mineralization occurred after Tl-bearing pyrite overgrowths, in association with acid dissolution (replacement) of laminated and nodular dolomite across the subbasin; and outer rims are enriched in Mn on preserved dolomite at the dissolution reaction front in contact with sphalerite. New thermodynamic fluid chemistry modeling demonstrates the metal distribution and paragenesis can be explained by acidic, oxidized ore fluids entering the pyrite-dolomite host lithology, allowing reduction and pH buffering by acid carbonate dissolution, resulting in stepwise metal deposition in an evolving fluid.

We argue this represents strong evidence for epigenetic ore formation at HYC. Furthermore, the primary control on ore deposition is not synsedimentary faulting in the subbasin; rather, the chemical potential of sedimentary carbonate within reduced, sulfidic lithologies appears to be of critical importance to precipitation of sphalerite.
Diagnosis and Management of Acute Compartment Syndrome
Authors: Osborn Patrick M. , Schmidt Andrew H.
Published: December 2020

The Major Extremity Trauma and Rehabilitation Consortium and the American Academy of Orthopaedic Surgeons have developed the Appropriate Use Criteria (AUC) for the Diagnosis and Management of Acute Compartment Syndrome (ACS). Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care, aid decision-making, and obtain the best possible outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The AUC for the Diagnosis and Management of ACS were derived by identifying clinical indications typical of patients suspected of an ACS in clinical practice. These indications were most often parameters observable by the clinician, including symptoms or results of diagnostic tests. The 135 patient scenarios and five treatments were developed by the writing panel, a group of clinicians who are specialists in this AUC topic. Next, a separate, multidisciplinary, voting panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a nine-point scale to designate a treatment as “appropriate” (median rating, seven to nine), “may be appropriate” (median rating, four to six), or “rarely appropriate” (median rating, one to three).
Relative Energy Deficiency in Sport: an Orthopaedic Perspective
Authors: Vopat Lisa , Mackay Matthew J. , Vopat Bryan G. , Mulcahey Mary K.
Published: December 2020

Relative energy deficiency in sport (RED-S) is a constellation of clinical findings related to low energy availability. Manifestations are variable but may include endocrine and reproductive dysfunction, impaired bone and muscle health, psychological complaints, and performance issues, among many others. Unlike the previously common terminology, the female athlete triad, RED-S encompasses a broader range of signs and symptoms and includes descriptions for the male athlete. Since first being described in 2014 by the International Olympic Committee, an abundance of research has sought to define, prevent, and treat the underlying condition of RED-S. Although medicine, and society in general, has tried to expose the hazardous training and lifestyle behaviors that can underpin RED-S, further research and education is required on the part of the clinician and athlete to reshape the culture and prevent the deleterious consequences of low energy availability.

In the current social situation, and even more in this time of the pandemic generated by Covid-19, education remains one of the most credible and central processes for access to knowledge and for civic, cultural and socio-economic development. In particular, higher education institutions
play a fundamental, unique and core role in seeking and pursuing a vision for education and training that encompasses being culturally different. This is crucial in the era of globalisation, cultural diversity, ubiquitous digital social networks and where the processes of access to knowledge
are multiple and challenging. This challenge is reflected in the strategic framework for European co-operation in education and training, which pursues four common EU objectives: to make lifelong learning a reality; to improve the quality of education and training; to promote equity, social
cohesion and active citizenship, and to enhance creativity and innovation at all levels of education and training.
Enhancing self-efficacy through life skills workshops

Published: December 2020

University attrition rates are often higher for students from groups under-represented in Higher Education (HE), for example those who have experienced social and educational disadvantage. Points of educational transition have been identified as key risk factors for progression and
retention, and interventions to increase self-efficacy may act protectively to reduce higher attrition rates.This study presents an evaluation of an intervention implemented at one UK medical school, which aimed to enhance participants' self-efficacy and sense of belonging. Participants
completed Schwarzer's General Self-Efficacy Scale and written evaluations. Qualitative data were examined inductively using thematic analysis. Average self-efficacy scores showed a statistically significant improvement six months after the intervention. Key themes including ‘it's
not just me’ and ‘learning from the experiences of others’ were identified from the qualitative data and explored within a framework of self-efficacy.The intervention appeared to have a positive impact on self-efficacy through two key sources. Firstly, creating positive
“physiological and emotional states’ enabled participants to engage in constructive discussions of personal difficulties they faced, such as imposter syndrome. Secondly, ‘vicarious experiences’, hearing how others had coped during difficult situations, improved participants'
beliefs in their ability to cope with future challenges and imagine being successful. These factors may be key in supporting transitions for under-represented university students engaged with a range of disciplines.

National Defensive and Defense Strategies. Selected Planning Problems
Authors: Dawidczyk Andrzej
Published: December 2020

The overall objective of undertaken research is to present national reflection on defense in
Poland, in particular an image of the defense planning culture. The article focuses on issues
of defense strategy planning as a part of the complete state defensive strategy and indicates
the necessary directions for changes in the essence of defense planning in the light of changes
in the security and defense environment of Poland in the 21st century.
In the study use has been made of an analysis and a critical review of normative documents,
strategies and doctrines. The collected data allow the indication of changes of an application
nature (projection method) to the theory of strategic planning in the field of national defense.
This allowed proving that the future desired position of Poland in regional and even continental
Europe depends on the anticipated direction of development of Polish defense potential,
defense system, and of course, a clearly expressed strategy. The most important element of the
three listed ones is naturally the strategy, the preparation of which requires regular cycles of
strategic reviews, which are unfortunately not feasible in Poland. The article also emphasizes
the importance of assuring the stability of the planning system, the basic element of which
are experts, and whose regular fluctuation as a result of constant political changes causes
a considerable destabilization of the planning system. Finally, attention is drawn to the fact
that the defense strategy must take into account the complexity and unpredictability of the
security environment – which are its basic features today.
Racjonalizacja działań w zakresie zapewnienia bezpieczeństwa w obliczu niekorzystnego zjawiska demograficznego w Polsce

Od wielu lat demografowie zwracają uwagę na niekorzystny trend, jakim jest depopulacja.
Zjawisko to nie dotyczy jedynie Polski, ale i też prawie całej Europy. Należy zdać sobie sprawę,
że kryzys demograficzny będzie miał wpływ na wiele dziedzin naszego życia, takich jak na
przykład ekonomiczne, społeczne, medyczne, kulturowe i co będzie tematem poniższego
artykułu – szeroko pojęte bezpieczeństwo. Niekorzystne wskaźniki demograficzne mogą
skutkować wyludnianiem się obszarów mniej zurbanizowanych, migracją ludzi z mniejszych
ośrodków do większych, emigracją zarobkową, ograniczonym dostępem do edukacji itp.
Każde państwo w ramach stworzonego systemu bezpieczeństwa wykorzystuje zasoby ludzkie,
jednak co będzie w przypadku, gdy zacznie brakować ludzi chcących podjąć służbę w Policji,
Państwowej Straży Pożarnej, Straży Granicznej? Jakie kroki należy przedsięwziąć już teraz, aby
te służby były przygotowane na reakcję, w przypadku gdy diagnoza demografów potwierdzi
się? Tego typu zagadnienie powinno zainteresować badaczy zajmujących się bezpieczeństwem.

Trusted Sensing Model for Mobile Ad HoC Network Using Differential Evolution Algorithm
Authors: Elamparithi P , Soundar Dr. K. Ruba
Published: December 2020

Mobile Ad Hoc Network (MANET) has set of mobile nodes that are allowed to communicate with each other through wireless links. The nodes are deployed spontaneously without any infrastructure in a geographical area. Due to the lack of centralized administration and prior organization, MANETs are vulnerable to different attacks of malicious nodes. To overcome the problem of black hole attack in MANETs, a trust model using Differential Evolution (DE) algorithm has been proposed. It identifies the malicious node and inhibits them to become the member of data transmission path. The proposed work consists of two phases; one is to obtain the optimized path and the other deals with the penalty factor for malicious nodes. Moreover, the Differential Evolution is one of the most promising optimization to enhance security with increased network density. The proposed algorithm is compared with AOMDV, DSR, Genetic algorithm and ACO.
Leakage-Resilient Outsourced Revocable Certificateless Signature with a Cloud Revocation Server
Authors: Tseng Yuh–Min , Wu Jui-Di , Huang Sen-Shan , Tsai Tung-Tso
Published: December 2020

Certificateless public-key system (CL-PKS) is a significant public-key cryptography and it solves both the key escrow and certificate management problems. Outsourced revocable certificateless public-key system (ORCL-PKS) with a cloud revocation server (CRS) not only provides a revocation mechanism, but also further outsources the revocation functionality to the CRS to reduce the computational burden of the key generation center (KGC). Recently, side-channel attacks have threatened some existing conventional cryptography (including CL-PKS). Indeed, adversaries can apply side-channel attacks to derive fractional constituents of private (or secret) keys to damage the security of these cryptographic protocols (or schemes). To withstand such attacks, leakage-resilient cryptography is an attractive approach. However, little research concerns with leakage-resilient certificateless cryptography. In this paper, the first leakage-resilient outsourced revocable certificateless signature (LR-ORCLS) scheme is presented. The proposed scheme allows adversaries to continually derive fractional constituents of private (or secret) keys and possesses overall unbounded leakage property. In the generic bilinear group (GBG) model, our scheme is shown to be existential unforgeable against adversaries. Finally, the comparisons between the proposed scheme and the previous revocable certificateless signature schemes are provided to demonstrate the merits of the proposed scheme.

Background: COVID-19 was a worldwide pandemic with international health emergencies and great challenges; health care personnel shortage and physician burnout is a potential major challenge that should be planned and managed; especially in those countries with a high COVID-19 occurrence. Objectives: This study was designed to assess the attitudes of 3rd-year anesthesiology residents toward an independent one month-length clinical care course for patients with COVID-19. Methods: A closed self-administered questionnaire was developed to assess the attitudes of 3rd-year clinical anesthesiology residents. A self-administered closed questionnaire was developed. Cronbach’s alpha was calculated to measure the reliability of the questionnaire; added with a factor analysis process. Results: All 19 clinical anesthesiology residents took part in the study, with a 100% response rate. Cronbach’s alpha for the reliability of the questionnaire was 0.678. The eigenvalue for 8 factors was equal to 1; however, further assessment led us to 7 factors. Conclusions: This one-month period could improve the competencies of the 3rd year clinical anesthesiology residents based on their viewpoints. Since the COVID-19 pandemic is ongoing health and social problem worldwide, 3rd-year anesthesiology residents could help the health system to recover health care delivery faults regarding manpower; a promising point for crisis preparedness in the COVID-19 pandemic. Besides, there were many constructive results for the clinical anesthesiology residents regarding their training and clinical service delivery.

: The coronavirus disease 2019 (COVID-19) pandemic has imposed a significant burden worldwide, manifesting as a severe disease and causing mortality even in children. Severe COVID-19 disease is characterized by cytokine storm with progression to secondary hemophagocytic lymphohistiocytosis (sHLH). We describe an 18-month-old boy in Iran, previously healthy, diagnosed with COVID-19-induced sHLH. Three weeks after close contact with COVID-19 confirmed cases, he was admitted with high fever, lethargy, mild respiratory distress, skin rash, and conjunctivitis with swollen eyelids and lips. Laboratory data revealed elevated levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and liver enzymes, and mild thrombocytopenia. His clinical condition rapidly deteriorated, with septic shock, hepatosplenomegaly, and respiratory failure. Laboratory tests showed cytopenia, coagulopathy, hyperferritinemia, and hypertriglyceridemia, which met the criteria for sHLH diagnosis. Chest computed tomography (CT) revealed bilateral infiltrations that suggested acute respiratory distress syndrome (ARDS) of COVID-19 that was confirmed by a positive real-time polymerase chain reaction (RT-PCR) test. Therefore, the child was treated with intravenous immunoglobulin (IVIG), glucocorticoid, hydroxychloroquine, lopinavir/ritonavir, and interferonβ-1a. This therapeutic strategy enabled complete recovery from fever, regaining consciousness, weaning from respiratory support, and resolving shock. Serial chest radiographs showed diminishing infiltrations. Sequential physical examinations revealed an overall significant reduction in spleen and liver span. Laboratory data showed rapid improvement from cytopenia and coagulopathy, normalization of liver enzyme levels, and reduction in hyperinflammation markers. Although ARDS is the most common cause of death from COVID-19, other complications such as sHLH may be lethal; thus, early diagnosis and appropriate treatment are necessary for saving patients’ lives.

Based on relativistic Born approximation theory, we have calculated the relati-vistic and non-relativistic generalized oscillator strengthes (GOS) of the Li-liks iso-electron sequence. The difference between the two calculations shows the relativistic effect of both the target and impact electron in the inelastic collision process. For low Z target (e.g. Li), the relativistic effect is negligible. For the 2s?p transition of Au+76, the relativistic GOS is 27.1% smaller than the non-relativistic one. At high impact energy, the contribution of transverse term of GOS to the differential cross section is important at certain angle. At extremely high impact energy (e.g. 106, 107eV), the transverse term of GOS becomes dominant at forward small angle and such forward peak makes overwhelming contribution to the totalinelastic cross section.

The photorefractive holographic grating in a Mn doped K1-yNayBa2-xSrxNb5O15 (KNSBN) is written with two 0.27mW He-Ne laser beams (632.6nm) and is read with one quasicontinuous dye laser beam (621.8nm, 1.6mW or less). It is found that the Bragg diffracton suddenly reaches its maximum at the beginning and then decays to its minimum with a time constant of about 0.6s. The ratio of the maximum to the minimum can be higher than 7.5. A theory including pyroelectric effect has been developed and it fits the experiment well.

The self-modified quasi-stationary model for radiation ablation has been established in this paper based on physical picture of numerical simulations. The objective of the model is to predict quantitatively the scaling laws of various ablation parameters driven by soft-X-ray, such as the dependence of ablation depth, pressure on radiation temperature, energy, pulse width, without resorting to complex computer simulations. The computational results are given fot some interstng materials in ICF. Scaling laws obtained in this paper are simple and effective in target design and analysis of experimental results.

ＰｂＴｉＯ３ thin films were deposited on (001) redoping n-Si, (001) SrＴｉＯ３ substrates by low-pressure MOCVD technique, XRD θ－２θ scan shows that the film on Si substrate has a polycrystalline structure, while the other two films have preferential orientations and their epitaxial nature was confirmed by the X-ray φ scan, rocking curves of the two epitaxial thin films were taken at BSRF using the synchrotron radiation. The film on LaAlＯ３ substrate has an a,c domain coexisting structure, and the film on ＳｒＴｉＯ３ substrate only has a c-orientation. All the films exhibit a c-axis shortening compare with the bulk material, and the reason can be attributed to the size effect and surface influence. The ferroelectric properties of the polycrystalline thin films were investigated using the redoping Si substrate as bottom electrode directly, and the ＰｂＴｉＯ３ thin film shows a perfect hysteresis loop.

A COMBINATION MODEL OF SUPERCONDUCTIVITY UNDER s+d MIXED WAVE SYMMETRY
Authors: SUN JIU-XUN  , ZHANG LI-YUAN  ,   北京大学物理系
Published: December 2020

Under the symmetry of the s+d mixed waves, a model is proposed which accounts for the combined influence of two factors on superconductivity. The first factor is the anisotropy of the pairing interaction between electrons, and the second is the Van Hove singularity in the two dimensional electronic structure. The theoretical results show that both the Van Hove singularity and the pairing interaction anisotropy are important factors to enhance Ｔc. The anisotropic pairing interaction naturally leads to the d-wave component. As this anisotropy strengthens, the d-wave component increases. The fairly high ratio of ２Δ（０）／ｋＢＴc of the high-Ｔc superconductors may be due to the fact that the weight of the s-wave component is far smaller than the weight of the d-wave component. The specific heat jump at Ｔc in combination model is completely different from the classical BCS theory.

The femtosecond laser pulses and pump-probe method have been used to measure the transient change of transmissivity of metallic ultrafine particles(UFPs) embedded in semiconductor thin film (Ag-BaO). The phenomena that the optical absorption of the films decreases and then restores within 2ps have been observed. The phenomena are due to the fact that electrons near the Fermi energy level in Ag UFPs are excited by femtosecond laser pulses and then the generated nonequilibrium electrons undergo a transient relaxation. The relaxation includes includes two parts: first, nonequilibrium electrons from Ag UFPs enter the matrix;then,nonequilibrium electrons are scattered by the lattice and inter-face between the Ag UFPs and the matrix. The different diameters of Ag UFPs affter the relaxation time of nonequilibrium electrons.

Published: December 2020

Using the principle of detailed balance and the evolution of entropy, the stability of a two-level system coupled to a squeezed vacuum via degenerate two-photon processes is investigated. We find that the stability of the system depends on the squeezing parameter M of squeezed vacuum. When |M| is small, the system is unstable, but when M is a very large real number, the system is driven to a stable state but far from equilibrium.

Authors: WU JIAN-QIANG  , LIU SHENG-GANG  ,   电子科技大学高能电子学研究所
Published: December 2020

A new type of slow-wave system (SWS) for the beam-wave interaction——putting a plasma column into a dielectric-partially-filled waveguide, is presented. By use of the linear self-consistent field theory, the interaction of a relativistic electron beam with the wave in the SWS is analysed. Determinative dispersion equations are derived for a thin annular relativistic electron beam propagating through the SWS surrounding and existing inside the plasma column, respectively. These dispersion equations are directly solved numerically, and the cut-off frequency, the operation frequency and the growth rate of the waves are obtained. Finally, the effects of the parameters of the plasma column on them are discussed.

The structural and magnetic properties of Co/Cu multilayers prepared by molecular beam epitaxy(MBE) and sputtering were investigated and compared with each other.It was found that the well defined layered structures existed in both samples,and the former was epitaxial single crystalline;while the latter was textured polycrystalline.Ferromagnetic resonance study showed the existence of a six-fold symmetry in the film plane,revealing the perfect in-plane structure of MBE samples.Giant magnetoresistance and its oscillation with the Cu thickness were found in sputtered samples.On the contrary,the magnetic resonance of MBE samples is smaller,about 7% for the second peak position.It is assumed that the superparamagnetic structure may be formed at interfaces in MBE samples which results in the different magnetic-field-dependent behaviors of magnetoresistance and- magnetization.

The direction of the energy flow in perfect crystals near the atomic absorption edge is studied in detail in the symmetrical Laue and Bragg cases. It is found that in the symmetrical Laue case, the direction of the energy flow corresponding to a tie point on the dispersion surface deviates from the normal of the real part of the dispersion surface, only when the contribution of the imaginary part of the atomic scattering factor to the diffraction is comparable to that of the real part. However, in the symmetrical Bragg case, the deviation takes place in the so-called “total reflection” region even when the contribution of the imaginary part of the atomic scattering factor to the diffraction is negligible. When diffraction is induced only by the imaginary part of the atomic scattering factor, the deviation becomes the largest in the Laue case, but the least in the Bragg case.

Vortex motion in high-temperature superconductors is studied starting from a variant of the time-dependent Ginzberg-Landau(TDGL) equations,in which the order-parameter relaxation time is taken to be complex.Using Lawrence-Doniach model and considering a TDGL model modified to take into account the Hall- effect,-we have evaluated and discussed the sign change of the Hall angle and anomalous Hall effect.The results are discussed in light of rather puzzling sign change of the Hall effect which has been observed in the mixed state of the high-temperature Superconductors.

The temperature dependence of the resistivity of an epitaxial YBa2Cu3O7-δ thin film has been measured in various magnetic fields up to 7T applied parallel to the c-axis near Tc. The result shows that the resistivity below Tc can be well fitted by thermally activation flux motion. The current density dependence of the effective pinning potential follows a logarithmic law proposed by Zeldov et al. The temperature and magnetic field dependence of the effective pinning potential follows U(H,T)=U0(1-T/Tc)H-α, with α=0.63, showing 2D behavior, It is consistent with the plastic deformation model of the flux-line lattice at flux-line-lattice dislocations.
