Mohamed El Naschie’s Revision of Albert Einstein’s E = m0c2: A Definite Resolution of the Mystery of the Missing Dark Energy of the Cosmos  [PDF]
J. H. He, L. Marek-Crnjac
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2013, DOI: 10.4236/ijmnta.2013.21006
Abstract:

The Egyptian engineering scientist and theoretical physicist Mohamed El Naschie has found a definite resolution to the missing dark energy of the cosmos based on a revision of the theory of Relativity. Einstein’s equation of special relativity E = m0c2, where m0 is the controversial rest mass and c is the velocity of light developed in smooth 4D space-time was transferred by El Naschie to a rugged Calabi-Yau and K3 fuzzy Kahler manifold. The result is an accurate, effective quantum gravity energy-mass relation which correctly predicts that 95.4915028% of the energy in the cosmos is the missing hypothetical dark energy. The agreement with WMAP and supernova measurements is astounding. Different theories are used by El Naschie to check the calculations and all lead to the same quantitative result. Thus the theories of varying speed of light, scale relativity, E-infinity theory, M-theory, Heterotic super strings, quantum field in curved space-time, Veneziano’s dual resonance model and Nash’s Euclidean embedding all reinforce, without any reservation, the above mentioned theoretical result of El Naschie which in turn is in total agreement with the most sophisticated cosmological measurement. Incidentally these experimental measurements and analysis were

Short Communication: Be careful for neglected diseases
J-H He
African Journal of Biotechnology , 2009,
Abstract: Neglected diseases boost (Nature, 457: 772, 2009), which will become greater threat to human health especially in tropical regions. In my opinion, it is the inherent result of climate warming. An allometrical scaling is suggested to support my opinion, this can also explain why swine flu does not affect pigs very much, but human beings fatally.
Holocene earthquakes on the Zemuhe Fault in Southwestern China
H. He,J. Ren
Annals of Geophysics , 2003, DOI: 10.4401/ag-3444
Abstract: The Zemuhe Fault is a prominent active fault in Southwestern China. Seven ravines along a 5 km long fault scarp indicate seven large magnitude earthquakes in the Holocene. The youngest four ravines were abandoned during four large magnitude earthquakes, the age of which are constrained by radiocarbon data: ravines 7, 6, and 4 formed in association with the earthquakes at A.D. 1850 and A.D. 814, B.C. 4477 ± 240 or older, and ravine 5 to a paleo-event between B.C. 4477 ± 240 and A.D. 814. Three trenches excavated by earlier workers together with a trench excavated and analyzed here revealed 3 or 4 earthquakes, which are consistent with those indicated by the youngest five ravines. These radiocarbon-dated earthquakes mainly occurred within two temporal clusters: the older cluster of two paleoearthquakes occurred approximately between B.C. 4250 and B.C. 6000, and the younger cluster includes two historical earthquakes of the A.D. 814 and A.D. 1850. Each cluster lasted about 1000-2000 years. A tranquil period of about 5000 years separates the two clusters, during which only one large magnitude earthquake occurred. Moreover, the average recurrence interval of large magnitude earthquake in the Holocene is about 1400-1700 years. Comparison of the maximum horizontal displacement of the A.D. 1850 earthquake, and the 85 ± 5 m cumulative lateral offset over the last 13-15 ka gives the average recurrence interval of 1000-1360 years. The different estimates may arise because moderate and small earthquakes produced a quite high cumulative lateral displacement along the Zemuhe Fault during the Holocene.
Quartic Gauge Boson Couplings
H. -J. He
Physics , 1998, DOI: 10.1063/1.56192
Abstract: We review the recent progress in studying the anomalous electroweak quartic gauge boson couplings (QGBCs) at the LHC and the next generation high energy e+-e- linear colliders (LCs). The main focus is put onto the strong electroweak symmetry breaking scenario in which the non-decoupling guarantees sizable new physics effects for the QGBCs. After commenting upon the current low energy indirect bounds and summarizing the theoretical patterns of QGBCs predicted by the typical resonance/non-resonance models, we review our systematic model-independent analysis on bounding them via WW-fusion and WWZ/ZZZ-production. The interplay of the two production mechanisms and the important role of the beam-polarization at the LCs are emphasized. The same physics may be similarly and better studied at a multi-TeV muon collider with high luminosity.
Heterogeneous reactions of carbonyl sulfide on mineral oxides: mechanism and kinetics study
Y. Liu,J. Ma,H. He
Atmospheric Chemistry and Physics (ACP) & Discussions (ACPD) , 2010, DOI: 10.5194/acp-10-10335-2010
Abstract: The heterogeneous reactions of carbonyl sulfide (OCS) on the typical mineral oxides in the mineral dust particles were investigated using a Knudsen cell flow reactor and a diffuse reflectance UV-vis spectroscopy. The reaction pathway for OCS on mineral dust was identified based on the gaseous products and surface species. The hydrolysis of OCS and succeeding oxidation of intermediate products readily took place on α-Al2O3, MgO, and CaO. Reversible and irreversible adsorption of OCS were observed on α-Fe2O3 and ZnO, respectively, whereas no apparent uptake of OCS by SiO2 and TiO2 was observed. The reactivity of OCS on these oxides depends on both the basicity of oxides and the decomposition reactivity of oxides for H2S. Based on the individual uptake coefficients and chemical composition of authentic mineral dust, the uptake coefficient (γBET) of mineral dust was estimated to be in the range of 3.84×10 7–2.86×10 8. The global flux of OCS due to heterogeneous reactions and adsorption on mineral dust was estimated at 0.13–0.29 Tg yr 1, which is comparable to the annual flux of OCS for its reaction with ·OH.
Solar transition region in the quiet Sun and active regions
H. Tian,W. Curdt,J. -S. He
Physics , 2009,
Abstract: The solar transition region (TR), in which above the photosphere the tempera- ture increases rapidly and the density drops dramatically, is believed to play an important role in coronal heating and solar wind acceleration. Long-lasting up-flows are present in the upper TR and interpreted as signatures of mass supply to large coronal loops in the quiet Sun. Coronal bright points (BPs) are local heating phenomena and we found a different Doppler-shift pattern at TR and coronal temperatures in one BP, which might be related to the twisted loop system. The dominant energy loss in the lower TR is the Ly-alpha emission. It has been found that most Ly-alpha radiance profiles are stronger in the blue peak, an asymmetry opposite to higher order Lyman lines. This asymmetry is stronger when the downflow in the middle TR is stronger, indicating that the TR flows play an important role in the line formation process. The peak separation of Ly-alpha is found to be larger in coronal holes than in the quiet Sun, reflecting the different magnetic structures and radiation fields between the two regions. The Lyman line profiles are found to be not reversed in sunspot plume and umbra regions, while they are obviously reversed in the surrounding plage region. At TR temperatures, the densities of the sunspot plume and umbra are a factor of 10 lower than of the plage, indicating that the sunspot plasma emitting at TR temperatures is higher and possibly more extended above sunspots than above the plage region.
The Equivalence Theorem And Its Radiative-Correction-Free Formulation For All R_xi Gauges
H. -J. He,W. B. Kilgore
Physics , 1996, DOI: 10.1103/PhysRevD.55.1515
Abstract: The electroweak equivalence theorem quantitatively connects the physical amplitudes of longitudinal massive gauge bosons to those of the corresponding ``unphysical'' would-be Goldstone bosons. Its precise form depends on both the gauge fixing condition and the renormalization scheme. Our previous modification-free schemes have applied to a broad class of $R_\xi$ gauges including 't Hooft-Feynman gauge but excluding Landau gauge. In this paper we construct a new renormalization scheme in which the radiative modification factor, $C_{mod}^a$, is equal to unity for all $R_\xi$-gauges, including both 't Hooft-Feynman and Landau gauges. This scheme makes $C_{mod}^a$ equal to unity by specifying a convenient subtraction condition for the would-be Goldstone boson wavefunction renormalization constant $Z_{\phi^a}$. We build the new scheme for both the standard model and the effective Lagrangian formulated electroweak theories (with either linearly or non-linearly realized symmetry breaking sector). Based upon these, a new prescription, called ``divided equivalence theorem'', is further proposed for extending the high energy region applicable to the equivalence theorem.
New Method for Detecting Charged (Pseudo-)Scalars at Colliders
H. -J. He,C. -P. Yuan
Physics , 1998, DOI: 10.1103/PhysRevLett.83.28
Abstract: We propose a new method for detecting a charged (pseudo-)scalar at colliders, based upon the observation that its Yukawa coupling to charm and bottom quarks can be large due to a significant mixing of the top and charm quarks. After analyzing the typical flavor mixing allowed by low energy data in the topcolor and the generic two-Higgs doublet models, we study the physics potential of the Tevatron, LHC, and linear colliders for probing such an s-channel charged resonance via the single-top (as well as Wh^0) production. We show that studying its detection at colliders can also provide information on the dynamics of flavor-changing neutral current phenomena.
Extra Families, Higgs Spectrum and Oblique Corrections
H. -J. He,N. Polonsky,S. Su
Physics , 2001, DOI: 10.1103/PhysRevD.64.053004
Abstract: The standard model accommodates, but does not explain, three families of leptons and quarks, while various extensions suggest extra matter families. The oblique corrections from extra chiral families with relatively light (weak-scale) masses, $M_{f} \sim $, are analyzed and used to constrain the number of extra families and their spectrum. The analysis is motivated, in part, by recent N = 2 supersymmetry constructions, but is performed in a model-independent way. It is shown that the correlations among the contributions to the three oblique parameters, rather than the contribution to a particular one, provide the most significant bound. Nevertheless, a single extra chiral family with a constrained spectrum is found to be consistent with precision data without requiring any other new physics source. Models with three additional families may also be accommodated but only by invoking additional new physics, most notably, a two-Higgs-doublet extension. The interplay between the spectra of the extra fermions and the Higgs boson(s) is analyzed in the case of either one or two Higgs doublets, and its implications are explored. In particular, the precision bound on the SM-like Higgs boson mass is shown to be significantly relaxed in the presence of an extra relatively light chiral family.
A 1-mm spectral line survey toward GLIMPSE Extended Green Objects (EGOs)
J. H. He,S. Takahashi,X. Chen
Physics , 2012, DOI: 10.1088/0067-0049/202/1/1
Abstract: A northern subsample of 89 Spitzer GLIMPSE extended green objects (EGOs), the candidate massive young stellar objects, are surveyed for molecular lines in two 1-GHz ranges: 251.5- 252.5 and 260.188-261.188 GHz. A comprehensive catalog of observed molecular line data and spectral plots are presented. Eight molecular species are undoubtedly detected: H13CO+, SiO, SO, CH3OH, CH3OCH3, CH3CH2CN, HCOOCH3, and HN13C. H13CO+ 3-2 line is detected in 70 EGOs among which 37 ones also show SiO 6-5 line, demonstrating their association to dense gas and supporting the outflow interpretation of the extended 4.5 um excess emission. Our major dense gas and outflow tracers (H13CO+, SiO, SO and CH3OH) are combined with our previous survey of 13CO, 12CO and C18O 1-0 toward the same sample of EGOs for a multi-line multi- cloud analysis of line width and luminosity correlations. Good log-linear correlations are found among all considered line luminosities, which requires a universal similarity of density and thermal structures and probably of shock properties among all EGO clouds to explain. It also requires that the shocks should be produced within the natal clouds of the EGOs. Diverse degrees of correlation are found among the line widths. However, both the line width and luminosity correlations tend to progressively worsen across larger cloud subcomponent size-scales, depicting the increase of randomness across cloud subcomponent sizes. Moreover, the line width correlations among the three isotopic CO 1-0 lines show data scatter as linear functions of the line width itself, indicating that the velocity randomness also increases with whole-cloud sizes and has some regularity behind.
