Ab Initio Calculations Of The Ground Electronic States Of The C3-ar And C3-ne Complexes

The C$_3$Ar and C$_3$Ne complexes have four large amplitude vibrations. These are the in- and out-of-plane C$_3$ bending motions, and the two van der Waals vibrations. Assignment of the spectra of the complexes is therefore challenging. The ab initio potential energies of their ground electronic states have been calculated at the CCSD(T)/pVQZ level. 46620 points have been computed to describe the four-dimensional potential of C$_3$Ar: $\angle C-C-C$ = 112-179.5$^{\circ}$, r (C-C bond length) = 1.298 \AA, R(C$_3$-Ar) = 3.4-6.0 \AA, $\phi$ (azimuth angle between Ar and the principal axis of C$_3$)=0-180$^{\circ}$, and $\theta$ (colatitude angle) = 0-180$^{\circ}$. For C$_3$Ne, 69190 points have been computed: $\angle C-C-C$=106-179.5$^{\circ}$, r(C-C)= 1.298\AA, R(C$_3$-Ne) = 3.0-7.0 \AA, $\phi$ = 0-180$^{\circ}$, $\theta$ = 0-180$^{\circ}$. Basis set superposition errors have been corrected in the C$_3$-Ne potential energy calculations. Morse type functions and power series were used to fit the calculated points

Laser-induced fluorescence spectra of C3Ar near 25400-25600 cm−1

About 14 bands of C$_3$Ar near the 0 4$^-$ 0-000 and 0 2$^+$ 0-000 bands of the \~{A}-\~{X} system of C$_3$ have been recorded by laser-induced fluoresence with a laser resolution of 0.035 cm$^{-1}$. Bands at 25428 amd 25515 cm$^{-1}$ are found to be type A, and those at 25431, 25496, and 25519 cm$^{-1}$ are type C. Bands at 25504 and 25507 cm$^{-1}$ are too diffuse for rotational analysis. The bands near 25500 cm$^{-1}$ form part of two progressions with about 10 cm$^{-1}$ separations, which appear to represent the van der Waals in-plane-bending vibration. A third diffuse feature was observed near the R(3) line of the 25519 cm$^{-1}$ band. Possible dissociation processes will be discussed

VIBRATIONAL PREDISSOCIATION OF THE Ã STATE OF THE C3Ar COMPLEX IN THE EXCITATION ENERGY REGION OF 25410-25535 CM−1

About 11 C$_3$Ar bands near the 0 4$^-$ 0-000 and 0 2$^+$ 0-000 transitions of the ~{A}$^1$$Pi$$_u$$-$~{X}$^1$$Sigma$$^+$$_g$ system of C$_3$ have been studied by both laser-induced fluorescence and wavelength-resolved emission techniques. Two prominent pairs of C$_3$Ar features were observed to the red of each of these two C$_3$ transitions. Each pair consists of a type A band and a type C band, with the type C band lying about 3 cm$^{-1}$ above the type A band. Rotational analysis showed that three of the bands are comparatively sharp, with line widths of 0.035 cm$^{-1}$, but the pair at 25504 and 25507 cm$^{-1}$ shows clear evidence of diffuseness. The spectral widths of the rotational lines do not depend on the excitation energies in any simple way. Most of the features in the wavelength-resolved emission spectra can be assigned as emission from vibrationally excited levels of the ~{A} state of the C$_3$ fragments down to the ground electronic state. Two different types of vibrational excitation of the C$_3$ fragments have been found: pure C$_3$-bending and antisymmetric C-C stretching. The branching ratios of the C$_3$ product states, the C$_3$-Ar vdW binding energy, and propensity rules for vibrational predissociation processes will be presented

RE-ANALYSIS OF THE DISPERSED FLUORESCENCE SPECTRA OF THE C3-RARE GAS ATOM COMPLEXES

The dispersed fluorescence (DF) spectra of the C$_3$Ne, C$_3$Ar, C$_3$Kr, and C$_3$Xe complexes near the 0 2$^-$ 0- 000, 0 4$^-$ 0- 000, 0 2$^+$ 0- 000 and 100-000 bands of the ~{A}-~{X} system of C$_3$footnote{G. Zhang, B.-G. Lin, S.-M. Wen, and Y.-C. Hsu, J. Chem. Phys. {bf120}, 3189(2004); J.-M. Chao, K. S. Tham, G. Zhang, A. J. Merer, Y.-C. Hsu, and W.-P. Hu, J. Chem. Phys. {bf134}, 074313(2011)} have been revisited. Some of the DF spectra of the Ne and Ar complexes have been recently obtained with a slightly improved resolution of 6-10 wn. All the DF spectra have been reassigned as emission from van der Waals (vdW) complexes and C$_3$ fragments. The optically excited C$_3$-Rg (Rg = rare-gas atom) complexes fluorescence and/or decay down to slightly lower (about 2-30 wn) vibrational levels without changing the internal energy of C$_3$ and then predissociate via the continua of the nearby vibronic states of C$_3$. The available dissociation channels depend on the binding energy of the ground electronic state complex. Exceptions have been found at the vdW bands near the 0 4$^-$ 0- 000 band of C$_3$. The binding energies of the ground electronic states of these four complexes will be discussed

A Flow-based Method to Measure Traffic Statistics in Software Defined Network

Since software defined network became a revolution of network, many new developments and deployments are put forward. Device operating in software defined network environment will need a controller to store control policy. As a result of flow is one of traffic presentation units in software defined network, hence, this paper proposed a prototype of flow-based method to measure traffic statistics which can be used in OpenFlow network. By analysis of flow table, active flows which managed by controller can be listed, and information of each flow can be presented with developed module on the controller. After gathered port statistics from OpenFlow switch and entries in flow table, information of each flow can be presented on a developed graphic interface. By using this method, Traffic statistics of each flow may be more adaptive and realizable for measurement for observation

Validation of a Chinese version of disease specific quality of life scale (HFS-36) for hemifacial spasm in Taiwan

<p>Abstract</p> <p>Background and object</p> <p>There was no Chinese questionnaire to evaluate the health-related quality of life (HRQoL) in patients with hemifacial spasm (HFS). In this study, we aimed to validate a new disease-specific HRQoL scale for HFS (HFS-36) in Chinese version, and compared it to SF-36, a generic HRQoL scale.</p> <p>Patients and Methods</p> <p>The HFS-36 Chinese version was modified from English version of HFS-30, including subscales of mobility, activities of daily living (ADL), emotional well-being, stigma, social support, cognition, bodily discomfort, and communication. All the items were scored on the 5-point scales, ranging from 0(never) to 4(always). Patients with HFS were asked to answer HFS-36 and SF-36 questionnaires on the same day before and 6-8 weeks after Botulinum toxin (BTX) injections, respectively. The reliability and validity of HFS-36 scale were evaluated statistically.</p> <p>Results</p> <p>Totally, 103 patients (68 females; 35 males) were recruited in this study, with a mean age of 57.6 ± 11.5 years and a mean duration of HFS for 7.6 ± 5.8 years. The intra-class correlation (ICC) and Cronbach's α were over 0.7 in the majority of items. HFS-36 showed a good correlation to HFS severity before BTX treatment and a significant improvement of subscale scoring after BTX treatment. HFS-36 also had a significant correlation to the mental health of SF-36.</p> <p>Conclusions</p> <p>The Chinese version of HFS-36 demonstrated a good reliability and validity in subscales of motility, ADL, emotion well-being, stigma and bodily discomfort. The HRQoL was significantly improved after BTX treatment assessed by HFS-36 or SF-36. Compared to SF-36, HFS-36 scale was more sensitive and specific to evaluate the HRQoL in HFS.</p

Managing cardiac arrest with refractory ventricular fibrillation in the emergency department: Conventional cardiopulmonary resuscitation versus extracorporeal cardiopulmonary resuscitation

AbstractAimRefractory ventricular fibrillation, resistant to conventional cardiopulmonary resuscitation (CPR), is a life threatening rhythm encountered in the emergency department. Although previous reports suggest the use of extracorporeal CPR can improve the clinical outcomes in patients with prolonged cardiac arrest, the effectiveness of this novel strategy for refractory ventricular fibrillation is not known. We aimed to compare the clinical outcomes of patients with refractory ventricular fibrillation managed with conventional CPR or extracorporeal CPR in our institution.MethodThis is a retrospective chart review study from an emergency department in a tertiary referral medical center. We identified 209 patients presenting with cardiac arrest due to ventricular fibrillation between September 2011 and September 2013. Of these, 60 patients were enrolled with ventricular fibrillation refractory to resuscitation for more than 10min. The clinical outcome of patients with ventricular fibrillation received either conventional CPR, including defibrillation, chest compression, and resuscitative medication (C-CPR, n=40) or CPR plus extracorporeal CPR (E-CPR, n=20) were compared.ResultsThe overall survival rate was 35%, and 18.3% of patients were discharged with good neurological function. The mean duration of CPR was longer in the E-CPR group than in the C-CPR group (69.90±49.6min vs 34.3±17.7min, p=0.0001). Patients receiving E-CPR had significantly higher rates of sustained return of spontaneous circulation (95.0% vs 47.5%, p=0.0009), and good neurological function at discharge (40.0% vs 7.5%, p=0.0067). The survival rate in the E-CPR group was higher (50% vs 27.5%, p=0.1512) at discharge and (50% vs 20%, p=0. 0998) at 1 year after discharge.ConclusionsThe management of refractory ventricular fibrillation in the emergency department remains challenging, as evidenced by an overall survival rate of 35% in this study. Patients with refractory ventricular fibrillation receiving E-CPR had a trend toward higher survival rates and significantly improved neurological outcomes than those receiving C-CPR
