MENINGOCOCCUS MENINGItIS IN CHILDREN REPORt OF AN EPIDEMIC IN CHANGSHA, HUNAN, 1935

Chinese Medical Journal 1936年第4期 491-505页

作者： t. F. Su M. D. Division of Pediatrics Department of Medicine The Hsiang Ya Medical College Changsha Hunan.

1. An epidemic of meningococcus meningitis appeared in Changsha, Hunan, from January to June, 1935, and reached its acme in March. A total of about 130 cases were admitted to the Hsiang Ya Medical College Hospital, among which 56 cases were children below 12 years of age.2. About an equal number of children of the rich and of poor classes suffered from the disease. the highest age incidences were under one year and 6 to 8 years. the incidence among males was 58.9 per cent.3. In 34, or 60.7 per cent of cases, they were admitted before or on the third day of the disease. the rest came in varying from the fourth day to over one month.4. Of the 19, or 33.9 per cent, the mentality was clear at the time of admission while the rest varied from drowsiness to coma.5. Muscular rigidity manifested in stiffness and retraction of neck and opisthotonus may be absent in young infants; the Kernig’s sign is of comparatively little value in early life, and the tendon reflexes were irregular.6. Bulging of the fontanel was present in every case in which it was still open.7. Convulsions were present in 34, or 60.7 per cent of cases. the highest incidence was in infants below one year. Strabismus, if present, was a significant finding.8. In 9, or 16.0 per cent, petechial spots and in 2, or 3.5 per cent hemorrhagic eruptions were found. Only three cases developed herpes.9. Vomiting was present in 50 cases, or 89.2 per cent. Patients were usually obstinately constipated. Only four cases complained of diarrhea.10. the temperature was irregular and the characteristic temperature curve was present in a few cases only.11. Four clinical forms of the disease were observed: (1) fulminating, (2) frank, (3) mild and (4) basilar types.12. Spinal fluid in the majority revealed a cell count from 2,000 to 20,000 per cmm. Four cases had cell counts below 500 per cmm and two cases 500 to 1,000 per cmm. the neutrophiles in the spinal fluid were usually above 80 and 90 per cent. A few cases revealed 40 or

A Robust Chaos-Based Image Cryptosystem with an Improved Key Generator and Plain Image Sensitivity Mechanism

引用

Journal of Information Security 2017年第1期8卷 23-41页

作者： Hidayet Ogras Mustafa türk Department of Electrical Education Batman UniversityBatmanTurkey Department of Electrical and Electronics Engineering Firat UniversityElazigTurkey

In this paper, we propose an effective gray image cryptosystem containing Arnold cat map for pixel permutation and an improved Logistic map for the generation of encryption keys to be used for pixel modification. Firstly, a new chaotic map is designed to show better performance than the standard one in terms of key space range, complexity and uniformity. Generated secret key is not only sensitive to the control parameters and initial condition of the improved map but also strongly depend on the plain image characteristic which provides an effective resistance against statistical and differential attacks. Additionally, to get higher encryption strength of the cryptosystem, both confusion and diffusion processes are performed with different keys in every iterations. theoretical analysis and simulation results confirm that the proposed algorithm has superior security and effectively encrypts and decrypts the gray images as well.

A FORtRAN Software Application to Decode Geographical, Lithological, Political, and Bibliographical Information from the IGBADAt International Database on Igneous Rocks

引用

Journal of Software Engineering and Applications 2018年第1期11卷 12-27页

作者： Ali t. Al-Mishwat Department of Earth and Environmental Sciences Kuwait University Kuwait Kuwait

GEOLItH is a FORtRAN program designed primarily to extract and decode geographical, lithological, political, and bibliographical information from the international igneous rocks database IGBADAt. It fetches the following information: sample name, sample latitude and longitude locational coordinates, name of specimen contributor to the database, nominal field and proper rock names, name of geological unit, name and title of rock groups, name of country and province of sample, and sample cultural location. Rock group name and title and geological unit name are decoded directly by simple manipulation and translation of text strings, while other types of information utilize pneumonic representations for decoding. Users interrogate the IGBADAt (and similarly-structured databases) fully, producing a voluminous wealth of data. Output from the GEOLItH software tool is a flat ASCII text file containing the decoded information. A spreadsheet-compatible file containing the output results is also produced. the latter file is ready for inclusion into a spreadsheet like EXCEL. An error file also results from the application of the GEOLItH program.

Optoelectronics Letters 2007年第2期3卷 141-143页

作者： FANG F. Z. XIONG Z. HU X. t. State Key Laboratory of Precision Measuring technology ＆ Instruments Tianjin University Tianjin 300072 Chin Singapore Institute of Manufacturing technology 71 Nanyang Drive 638075 Singapore

Ultra-precision machining is an effective approach to achieve high dimension accuracy and surface finish required in optical and laser components. An extensive study using a two-axis diamond turning machine is conducted to machine the reflector arrays used for laser diode beam shaping. to position the workpiece precisely, theoretical analysis is made so that the dimensional accuracy can be achieved. Investigations into machining burr reduction are carried out. With the process developed, reflectors with optical surface finish of 8 nm in Ra and minimized burr size of less than 0.5 μm have been achieved.

A Formulation of Quantum theory Based on two Physical Principles

引用

Journal of Modern Physics 2015年第4期6卷 434-447页

作者： R. t. Deck Department of Physics University of Toledo Toledo USA

We demonstrate two points: 1) the formalism of quantum mechanics can be understood simply as a structure for the expression of the physical notion that not all observables can have values simultaneously;2) the specific uncertainty relations can be derived (rigorously) by combination of the invariance principle with a general uncertainty relation based only on the existence of unspecified pairs of conjugate observables. For this purpose, we present a formulation of quantum mechanics based strictly on the invariance principle and a “weak” statement of the uncertainty principle that asserts only the existence of incompatible (conjugate) observables without specifying which observables are incompatible. We go on to show that the invariance principle can be used to develop the equations of motion of the theory, including the Klein-Gordon and Schrodinger equations.

Winners and losers among tree species in Xishuangbanna: which traits are most important?

引用

Science Bulletin 2015年第10期60卷 916-924,I0007页

Massive human interference in natural ecosystems is resulting in a few ＂winners＂ and many ＂losers＂. However, the drivers of this winner-loser replacement pattern remain poorly understood. the aim of the study reported here was to identify winners among the tree flora of Xishuangbanna and compare their functional traits, specific leaf area （SLA）, wood density （WD）, seed mass （SM） and maximum height （MH） with previously identified losers （i.e., endangered species）. Fifteen native tree species were identified as winners from expert opinion, plot-based surveys of secondary forests and plotless surveys along roads. twelve endangered tree species for which trait information could be obtained were used for comparison. traits were compared with a Wilcoxon rank-sum test. Winners had significantly higher SLA, but lower WD. SM and MH did not differ significantly between groups. When the effects of phylogeny were removed by using phylogenetic generalized least squares, the difference in SLA became marginally insignificant. Principal component analysis resulted in two overlapping groups, showing that the selected traits were insufficient to distinguish winners and losers. Our results suggest that the ＂few winners, many losers＂ paradigm applies to trees in Xishuangbanna, with15 species accounting for most trees in the disturbed habitats sampled.

the theory of Coherent Synchronized Reactions: Chemical Interference Logics

引用

Materials Sciences and Applications 2015年第2期6卷 152-170页

作者： t. M. Nagiev Nagiev Institute of Catalysis and Inorganic Chemistry National Academy of Sciences of Azerbaijan Baku Azerbaijan

Various types of possible interactions between reactions are discussed. Some of them are united by the general idea of chemical reaction interference. the ideas on conjugated reactions are broadened and the determinant formula is deduced;the coherence condition for chemical interference is formulated and associated phase shifts are determined. It is shown how interaction between reactions may be qualitatively and quantitatively assessed and kinetic analysis of complex reactions with under researched mechanisms may be performed with simultaneous consideration of the stationary concentration method. Using particular examples, interference of hydrogen peroxide dissociation and oxidation of substrates is considered. therefore macrokinetic theory of coherent synchronized reactions is offered.
