Abstract: Background and importance More than 60% of prescription are not suitable for crushing, but the medicines may be crushed for patients for home care and in medical institutions. To reduce incorrect methods of taking medicines, we provided caregivers who fully understood tube feeding, knowledge and skills, using illustrated materials, to explain the correct methods of taking medicine before discharge from hospital. Aim and objectives To improve the knowledge and skills of caregivers in tube feeding by providing illustrated materials for drug education in the discharge planning service and then home care, to achieve seamless pharmaceutical care. Material and methods From October to December 2018, candidates were identified through screening information from the hospital information system for tube feeding. After excluding those unable to communicate or illiterate, specific tube feeding medication counselling was provided to caregivers. Questionnaires were filled out before and after the educational intervention. The study was conducted with the approval of Taipei City Hospital research ethics committee (TCHIRB-10703101). Results Forty caregivers were enrolled in the study with an average age of 56.6 years and 67.5% were women. Lung infections were present in 42.5% of patients and 47.5% of patients had tube feeding during hospitalisation for the first time. The questionnaire was made up of four items: frequency of drug administration, identification of crushed medicine, obstruction of pipeline and risk of crushing. Each item was given a score of 1 to 3. Knowledge assessment of medication tube feeding (knowledge and skill) was significantly increased after drug education (7.33±2.54 vs 9.78±1.99, p Conclusion and relevance The data indicated that illustrated materials were good for patient education. We suggest that the tube feeding knowledge and skill should be widely used to increase patient drug safety and use correctly. References and/or acknowledgements No conflict of interest.

Abstract: We have studied the process $e^+e^-{\rightarrow}\rm n {\gamma}$ $(\rm n{\ge}2)$ at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 ${\rm pb^{-1}}$ and 10.1 ${\rm pb^{-1}}$ respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower limits on contact interaction energy scale parameters, on the QED cut-off parameters and on the mass of excited electrons.

Abstract: A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies s = 161 GeV and s 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV.

Abstract: Using a data sample of 1 475 000 Z → qq(γ) events collected during 1994 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, D s − → τ − ν τ and B − → τ − ν τ . A signal is observed in the invariant mass distribution M(γD s − ) corresponding to the decay sequence D ∗− → γD s − , D s − → τ − ν τ , τ − → l − ν l ν τ . The branching fraction for D s − → τ − ν τ decays is measured to be β (D s − → τ − ν τ ) = 0.074 ± 0.028(stat) ± 0.016(syst) ± 0.018(norm) . No signal of B − → τ − ν τ decays is observed in the data, corresponding to an upper limit on the branching franction β( B − → τ − ν τ ) −4 at 90% CL.

Abstract: We have studied the process e+e− → nγ (n ≥ 2) at an average center-of-mass energy of 133 GeV using the L3 detector at LEP. For an integrated luminosity of 4.95 pb−1 we find one γγγγ(γ) final state with only hard photons. The rates of both γγγ and γγ events are consistent with QED expectations. The cross section of the reaction e+e− → γγ(γ) in the polar range 16° < θγ < 164° is measured to be 22.6 ± 2.2 pb. Decays into photons of narrow scalar resonances with masses between 90 and 130 GeV are not observed. The observation of the event with four energetic photons is consistent with QED although the kinematic configuration of the photons is atypical.

Abstract: The inclusive semileptonic branching ratios b→eνX,μ νX,τ νX andνX have been measured at LEP with the L3 detector. The analysis is based on 2-jet hadronic Z decays obtained in the data collected between 1991 and 1992. Three separate event samples are analysed, containing electrons, muons and large missing energy (neutrinos), respectively. From the electron sample, we measure Br(b→eνX)=(10.89±0.20±0.51)% and, from the muon sample, Br(b→μ νX)=(10.82±0.15±0.59)%, where the first error is statistical and the second is systematic. From the missing energy sample, we measure Br(b→νX)=(23.08±0.77±1.24)%, assuming the relative semileptonic decay rates e:μ:τ=1:1:(0.25±0.05), according to theoretical expectations. From a combined analysis of all three samples and constraining the relative semileptonic rates, we measure Br(b→eνX)=Br(b→μ νX)=(10.68±0.11±0.46)%. Alternatively, we can remove the constraint on the relative semileptonic rates and measure Br(b→τ νX)=(1.7±0.5±1.1)%.

Abstract: The reaction \epem\ra\epem\gamma^*\gamma^*\ra\epem\kos\kos is studied with the L3 detector at LEP and the formation of the f_2\, \!\!\!'(1525) resonance is observed. For an integrated luminosity of 114 \pb, % \ collected over the years 1991-1994, 31\pm6 f_2\, \!\!\!' events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be \Gamma_{\gamma\gamma}(f_2\,\!\!\!')\times Br(f_2\ \!\!\!'\ra \k\bar{\k})=(0.093\pm 0.018\pm 0.022) keV. Only three events are found in the f_2(1270)-a_2(1320) mass region, consistent with destructive f_2-a_2 interference in the \kos\kos \ final state. The mixing angle of the tensor meson nonet is determined to be \theta=(29.4^{+1.4}_{-1.6})^\circ.

Abstract: A search for the decays B d,s 0 → γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(B d 0 → γ ) −5 and Br(B s 0 → γγ ) −5 at 90% CL. These are the first limits set on these exclusive rare decays.

Abstract: Total and differential cross sections for the process e+e− → γγ(γ), and the total cross section for the process e+e− → γγγ, are measured at energies around 91 GeV using the data collected with the L3 detector from 1991 to 1993. We set lower limits, at 95% CL, on a contact interaction energy scale parameter Λ > 602 GeV, on the mass of an excited electron and on the QED cut-off parameters Λ+ > 149 GeV and Λ_ > 143 GeV. Upper limits are also set o branching fractions of Z decaying into γγ, π° and ηγ of 5.2 × 10−5, 5.2 × 10−5 and 7.6 × 10−5 respectively. The reactions e+e− → ℓ+ℓ−nγ (ℓ = e, μ, τ) are studied using the data collected from 1990 to 1994. The data are consistent with the QED expectations., Facultad de Ciencias Exactas

Abstract: We have measured the time integrated B0 B 0 mixing parameter and the forward-backward asymmetry in the process e+e− → b b using hadronic events containing muons or electrons. The data sample corresponds to 1,044,000 hadronic decays of the Z. From a fit to the momentum and transverse momentum distributions for single lepton and dilepton events, we have determined the B0 B 0 mixing parameter to be χB = 0.123 ± 0.012 (stat.) ± 0.008 (sys.), and the b b forward-backward asymmetry at the effective center-of-mass energy √s = 91.30 GeV to be A b b = 0.087 ± 0.011 ( stat. ) ± 0.004 ( sys. ) This measurement corresponds to a value of the effective electroweak mixing angle of sin 2 θ w = 0.2335 ± 0.0021 .

Abstract: We have measured the forward-backward asymmetry in e + e − → b b and e + e − → c c processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and pT spectra, we determine A b b =0.086±0.015±0.007 and A c c =0.083±0.038±0.027 at the effective center-of-mass energy √s=91.24 GeV. These measurements yield a value of the electroweak mixing angle sin 2 θ w =0.2336±0.0029 .

Abstract: A more precise determination of the B°-B ° mixing parameter in Z ° decays based on a fourfold increase in statistics has been made using the 1990 and t99t L3 data. The analysis of the dilepton events, rnuons and electrons, gives: Za = 0.121 + 0.017 (stat) :t: 0.006 (sys). Using the value Of Xd measured at the "f(4S) we derive the following limit for Zs: Zs > 0.16 (90% CL)., Facultad de Ciencias Exactas

Abstract: We present a study of the global event shape variables thrust and heavy jet mass, of energy-energy correlations and of jet multiplicities based on 250 000 hadronic Z 0 decays. The data are compared to new QCD calculations including resummation of leading and next-to-leading logarithms to all orders. We determine the strong coupling constant α s (91.2 GeV) = 0.125±0.003 (exp) ± 0.008 (theor). The first error is the experimental uncertainty. The second error is due to hadronization uncertainties and approximations in the calculations of the higher order corrections.

Abstract: We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation. Comparing our results to e + e − data between √ s = 9 and 91 GeV, we findfind that the evolution of the spectra with center of mass energy is consistent with the QCD predictions.

Abstract: From 2540 Z0 → τ+τ− events, we determine the inclusive decay branching fractions of the τ-lepton into one and three charged particles to be 0.856 ± 0.006 (stat.) ± 0.003 (syst.) and 0.144 ± 0.006 (stat.) ± 0.003 (syst.), respectively. The leptonic branching fractions are measured to be 0.175 ± 0.008 (stat.) ± 0.005 (syst.) for τ → μνμντ and 0.177 ± 0.007 (stat.) ± 0.006 (syst.) for τ → eνeντ. We determined the τ lifetime both from three-prong decays using the decay length and from one-prong decays using the impact parameter. The results from the two independent methods agree and yield a combined value of [0.309 ± 0.023 (stat.) ± 0.030 (syst.)] × 10−12s.

Abstract: We have measured the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈Mz. From a fit to the single and dilepton p and P⊥ spectra, we determine A b b =0.130 −0.042 +0.044 including the correction for B 0 − B 0 mixing.

Abstract: Whatever the field, major change implies as much as deep transformation of thinking i.e to put in network new skills in particular, those made available by the availability of new technologies. In this context, only one individual cannot join together all necessary skills. It becomes clear that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background. The local empowerment concerns a collective phenomenon of acquisition and development of skills rests on an learning way appropriate to the potential of the territory to form or promote. The local mediation sets for objective the creation of relations between pre-existent skills and their transfer between the actors, individuals or groups, private or public. But the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.

Abstract: We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.

Abstract: A study of neutral-current four-fermion processes is performed, using data collected by the L3 detector at LEP during high-energy runs at centre-of-mass energies 130 - 136, 161 and 170 - 172 GeV, with integrated luminosities of 4.9, 10.7 and 10.1 pb$^{-1}$, respectively. The total cross sections for the final states $ \ell\ell \ell^\prime \ell^\prime $ and $\rm \ell\ell qq $ ($\ell$,~$\ell^\prime $ = e, $\mu$ or $\tau$) are measured and found to be in agreement with the Standard Model prediction.

Abstract: We have studied the structure of hadronic events with a hard, isolated photon in the final state (e+e− → Z → hadrons + γ) in the 3.6 million hadronic events collected with the L3 detector at centre-of-mass energies around 91 GeV. The centre-of-mass energy of the hadronic system is in the range 30 GeV to 86 GeV. Event shape variables have been measured at these reduced centre-of-mass energies and have been compared with the predictions of different QCD Monte Carlo programs. The event shape variables and the energy dependence of their mean values are well reproduced by QCD models. We fit distributions of several global event shape variables to resummed O(αs2) calculations to determine the strong coupling constant αs over a wide range of energies. We find that the strong coupling constant αs decreases with increasing energy, as expected from QCD., Facultad de Ciencias Exactas

Abstract: A study of resonance formation is presented in the π+ π- π0 final state in two-photon collisions at LEP. The a2(1320) radiative width is measured to be Γγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production is dominant. Exclusive π+ π- π0 production has also been studied in the mass region above the a2 in the pπ and f2π channels. This region is dominated by a JP = 2+ helicity 2 wave., Facultad de Ciencias Exactas

Abstract: A measurement of the $\mathrm{K^0_s}$ and $\Lambda$ inclusive production rates and momentum spectra in two- and three-jet events is presented. On the basis of about 3.1~million Z decays collected with the L3 detector at LEP, we observe that the production of these particles is well modeled by string fragmentation.

Abstract: The Michel parameters ϱ, η, ξ, and ξδ, the chirality parameter ξh and the τ polarization Pτ are measured using 32012 τ pair decays. Their values are extracted from the energy spectra of leptons and hadrons in τ− → l−νlντ and τ− → π−ντ decays, the energy and decay angular distributions in τ− → ϱ−ντ decays, and the correlations in the energy spectra and angular distributions of the decay products. Assuming universality in leptonic and semileptonic τ decays, the results are ϱ = 0.794±0.039±0.031, η = 0.25±0.17±0.11, ξ = 0.94±0.21±0.07, ξδ = 0.81±0.14±0.06, ξh = −0.970±0.053±0.011, and Pτ = −0.154±0.018±0.012. The measurement is in agreement with the V-A hypothesis for the weak charged current., Facultad de Ciencias Exactas

Abstract: We have analyzed one-prong τ decays with neutral kaons using the information from a fine-grained hadron calorimeter. The data sample consists of 43 500 Z → τ+τ−(γ) events collected by the L3 detector at LEP in 1991, 1992 and 1993. The following branching fractions are measured: B(τ− → ν-π Kº) = 0.0095 ± 0.0015 (stat) ± 0.0006(syst); B(τ− → vπºKº) = 0.0041 ± 0.0012(stat) ± 0.0003(syst) and B(τ− → vπ-K°Kº) = 0.0031 ± 0.0012(stat) ± 0.0004( syst)., Facultad de Ciencias Exactas

Abstract: Using a sample of e+e− annihilation events collected at the Z resonance corresponding to an integrated luminosity of 11.2 pb−1, we have searched for γX final states where X represents stable, weakly interacting particles and the energy of the photon is greater than 1 2 E beam . No events were found. The results have been interpreted within a composite Z model and a supergravity model with a light gravitino.

Abstract: We search for new resonances, Y, with mass MY, in the range from 30 to 89 GeV, produced via the reaction e+e− → Z0 →γY, where Y subsequently decays into e+e−, μ+μ− or hadrons. We use 5.5.pb−1 of data collected in the energy range 88.2 ≤ √s ≤ 94.2 GeV, near the Z0 peak. We obtain the following upper limits, at the 95% confidence level, on the product of the branching ratios: BR(Z0 → γY) × BR(Y → e+e−) < 2.8 × 10−4 for 30 < MY < 89, BR(Z0 →γY × BR(Y → μ+μ−) < 2.3 × 10−4 for 30 < MY < 89, BR(Z0→ γY) × BR(Y → hadrons) < 4.7 × 10−4 for 30 < MY < 86. These limits are valid for resonances with widths smaller than our mass resolution., Facultad de Ciencias Exactas

Abstract: We have measured the decay properties of from a study of inclusive muon and electron events. The average (e and μ) b-quark semileptonic branching ratio has been determined to be BR (b → ℓ + X) = 0.119 ± 0.003 (stat.) ± 0.006 (syst.), assuming the standard model prediction of Γbb = 378 ± 3 MeV. From the ratio of the number of dilepton events to single lepton events, we find BR (b → ℓ + X) = 0.113 ± 0.010 (stat.) ± 0.006 (syst.), without assumptions on Λbb. The partial decay width of the Z0 into has been measured to be Λbb = 385 ± 7 (stat.) ± 11 (syst.) MeV with an additional 19 MeV error from the uncertainty in BR (b → ℓ + X). The average fractional energy of bottom hadrons in events has been determined to be 〈xE〉 = 0.686 ± 0.006 (stat.) ± 0.016 (syst.)., Facultad de Ciencias Exactas

Abstract: We have searched for direct leptoquark production in Z0 decays from a scan of the Z0 resonance, in the energy range 88.2 ⩽ √s ⩽ 94.2 GeV, using 5.2 pb−1 of data. We exclude the existence of scalar leptoquarks with masses less than 41 to 44 GeV, depending on the charge assignments, at the 95% confidence level.

Abstract: From a fit to the impact parameter distribution of lepton tracks from semileptonic b decay, the lifetime of B-hadrons produced in e + e − collisions at the Z 0 is measured to be 1.32±0.08 (stat.)±0.09(syst.) ps. Combined with an earlier measurement of the branching ratio Br(B→l ν X), the CKM matrix element | V cb | is determined to be 0.046±0.002 (exp.) −0.003 +0.004 (theory).

Abstract: We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0→μτ, Z0→eτ, and Z0→eμ. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0’s produced. We obtain upper limits on the branching ratios of 4.8 X 10-5 for the μτ 3.4 X 10-5 for the eτ and 2.4 X 10-5 for the eμ decay modes at the 95% confidence level., Facultad de Ciencias Exactas

Abstract: We present a study of energy-energy correlations based on 83 000 hadronic Z0 decays. From this data we determine the strong coupling constant αs to second order QCD: αs(91.2 GeV)=0.121±0.004(exp.)±0.002(hadr.)-0.006 + 0.009(scale)±0.006(theor.) from the energy-energy correlation and αs(91.2 GeV)=0.115±0.004(exp.)-0.004 +0.007(hadr.) -0.000 +0.002(scale)- 0.005 +0.003 (theor.) from its asymmetry using a renormalization scale μ1=0.1 s. The first error (exp.) is the systematic experimental uncertainly, the statistical error is negligible. The other errors are due to hadronization (hadr.), renormalization scale (scale) uncertainties, and differences between the calculated second order corrections (theor.). © 1991.

Abstract: We have studied the reactions e+e−→hadrons, e+e−, μ+ μ− and τ+τ−, in the energy range 88.2 ≦ √s ≦ 94.2 GeV. A total luminosity of 5.5 pb−1, corresponding to approximately 115000 hadronic and 10000 leptonic Z0 decays, has been recorded with the L3 detector. From a simultaneous fit to all of our measured cross section data, we obtain assuming lepton universality: Mz = 91.181 ± 0.010 ± 0.02 (LEP) GeV, Γz = 2501 ± 17 MeV, Γhad= 1742 ± 19 MeV, Γt = 83.6 ± 0.8 MeV. If we do not assume lepton universality, we obtain for the partial decay widths of the Z0 into e+e−, μ+μ− and τ+ τ−: Γe = 83.3 ± 1.1 MeV, Γμ = 84.5 ± 2.0 MeV, Γτ = 84.0 ± 2.7 MeV. From the measured ratio of the invisible and the leptonic decay widths of the Z0, we determine the number of light neutrino species to be Nv =3.05±0.10. We include our measurements of the forward-backward asymmetry for the leptonic channels in a fit to determine the vector and axial-vector neutral current coupling constants of charged leptons to the Z0. We obtain g¯V = −0.046+0.015−0.012 and g¯A = −0.500 ± 0.003. In the framework of the Standard Model, we estimate the top quark mass to be mt =193+52−69 ± 16 (Higgs) GeV, and we derive a value for the weak mixing angle of sin2θW ≡ 1 − (MW/MZ)2 = 0.222 ± 0.008, corresponding to an effective weak mixing angle of sin2θ¯W = 0.2315 ± 0.0025., Facultad de Ciencias Exactas

Abstract: We have measured the cross-section of the reaction e + e − → γγ at center of mass energies around the Z 0 mass. The results are in good agreement with QED predictions. For the QED cutoff parameters the limit of Λ + > 103 GeV and Λ − 118 GeV are found. For the decays Z 0 → γ ,Z 0 → π 0 γ , Z 0 → γγγ we find upper limits of 2.9 × 10 −4 ,2.9×10 −4 ,4.1×10 −4 and 1.2×10 −4 , respectively. All limits are at 95% CL.

Abstract: We present the results from a search for the light neutral scalar Higgs boson h° and the pseudoscalar Higgs boson A° of the minimal super-symmetric standard model. The analysis is based on a data sample corresponding to 71 000 hadronic Z° decays recorded with the L3 detector at LEP. No evidence for the existence of the neutral Higgs bosons h° and A° has been found. The region of h° and A° masses up to 41.5 GeV is excluded at 95% confidence level.

Abstract: We have measured the properties of Z0 → b b decays using a sample of 944 inclusive muon events, corresponding to 18 000 hadron events obtained with the L3 detector at LEP. We measured the partial decay width of the Z0 into b b , Γ b b =353±48 MeV , and we determined the vector coupling of the Z0 to the b quark; grmv2(b)=0.095±0.047. We measured the forward-backward charge asymmetry in e+e− → b b events at √s≈Mv, and obtained A b b =13.3±9.9% .

Abstract: We have searched for the excited electron neutrino produced from Z 0 decays in the channel e + e − →νν ∗ using the L3 detector at LEP. The decays ν ∗ →eW and ν ∗ →νγ have been investigated. We have determined an upper limit on the Zνν ∗ coupling as a function of m ν ∗ up to the Z 0 mass.

Abstract: We have measured the partial widths for the three reactions e + e − → Z 0 → e + e − , μ + μ − , τ + τ − . The results are Γ ee = 84.3±1.3 MeV, √ Γ ee Γ μμ =83.9±1.4 MeV, and √ Γ ee Γ ττ =83.9±1.4 MeV, where the errors are statistical. The systematic errors are estimated to be 1.0 MeV, 0.9 MeV, and 1.4 MeV, respectively. We perform a simultaneous fit to the cross sections for the e + e − →e + e − , μ + μ − , and τ + τ − data, the differential cross section as a function of polar angle for the electron data, and the forward- backward asymmetry for the muon data. We obtain the leptonic partial with Γ ll =84.0±0.9 (stat.) MeV. The systematic error is estimated to be 0.8 MeV. Also, we obtain the axial-vector and vector weak coupling constants of charged leptons, g A =−0.500±0.003 and g ν =−0.064 −0.013 +0.017 .

Abstract: A search for the neutral Higgs boson, using the processes Z 0 → H 0 e + e − , Z 0 → H 0 μ + μ − , Z 0 → H 0 τ + τ − , Z 0 → H 0 v v and Z 0 → H 0 q q , is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0 → hadrons. Combining all these processes, the mass range excluded is 32 MeV−15 GeV at 95% CL and 40 MeV−12 GeV at 99% CL. The result from this experiment is unambiguous in the context of the standard model.

Abstract: The structure of hadronic events fromZ 0 decay is studied by measuring event shape variables, factorial moments, and the energy flow distribution. The distributions, after correction for detector effects and initial and final state radiation, are compared with the predictions of different QCD Monte Carlo programs with optimized parameter values. These Monte Carlo programs use either the second order matrix element or the parton shower evolution for the perturbative QCD calculations and use the string, the cluster, or the independent fragmentation model for hadronization. Both parton shower andO(α 2 s matrix element based models with string fragmentation describe the data well. The predictions of the model based on parton shower and cluster fragmentation are also in good agreement with the data. The model with independent fragmentation gives a poor description of the energy flow distribution. The predicted energy evolutions for the mean values of thrust, sphericity, aplanarity, and charge multiplicity are compared with the data measured at different center-of-mass energies. The parton shower based models with string or cluster fragmentation are found to describe the energy dependences well while the model based on theO(α 2 s calculation fails to reproduce the energy dependences of these mean values.

Abstract: Objective: Attention-deficit/hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental disorder with a prevalence ranging from 6.1 to 9.4%. The main symptoms of ADHD are inattention, hyperactivity, impulsivity, and even destructive behaviors that may have a long-term negative influence on learning performance or social relationships. Early diagnosis and treatment provide the best chance of reducing and managing symptoms. Currently, ADHD diagnosis relies on behavioral observations and ratings by clinicians and parents. Medical diagnosis of ADHD was reported to be delayed because of a global shortage of well-trained clinicians, the heterogeneous nature of ADHD, and combined comorbidities. Therefore, alternative ways to increase the efficiency of early diagnosis are needed. Previous studies used behavioral and neurophysiological data to assess patients with ADHD, yielding an accuracy range from 56.6% to 92%. Several factors were shown to affect the detection rate, including methods and tasks used and the number of electroencephalogram (EEG) channels. Given that children with ADHD have difficulty sustaining attention, in this study, we tested whether data from multiple tasks with different difficulties and prolonged experiment times can probe the levels of brain resources engaged during task performance and increase ADHD detection. Specifically, we proposed a Deep Neural Network-based (DNN) fusion model of multiple tasks to enhance the detection of ADHD., Methods & Results: Forty-nine children with ADHD and thirty-two typically developing children were recruited. Analytic results show that the fusion of multi-task neurophysiological data can increase the separation rate to 89%, whereas a single data type can only achieve a best accuracy of 81%. Moreover, the use of multiple tasks helps distinguish between children with ADHD and typically developing children. Our results suggest that different neurophysiological models from multiple tasks can provide essential information to assist in ADHD screening. In conclusion, the proposed model offers a more efficient, and accurate alternative for early clinical diagnosis and management of ADHD. The application of artificial intelligence and multimodal neurophysiological data in clinical settings sets a precedent for digital health, paving the way for future advancements in the field., (© 2024 The Authors.)

47. Influences of Social-Psychological Constructs in Predicting Taiwanese Pro-Environmental Behaviors.

Author: Yeh SC, Tan AYK, Lai RL, Her RS, Fang WT, and Liu SY
Abstract: A value-belief-norm (VBN) model for understanding the pro-environmental behaviors (PEB) of Taiwanese was developed. This formulated VBN model included personal values, openness to change, awareness of consequences, personal norms, social norms, and PEB. Ecological world view and ascription of responsibility were excluded to develop a tighter model. A total of 1079 completed questionnaires were collected and structural equation modelling was utilized, where standard estimates and coefficients of determination validated the formulated VBN model's effectiveness. Each construct served its role as the mediator between its distal variable and outcome variable, with a substantial level of predictive accuracy, and 74.3% of the variance in PEB was accounted for. Further findings found that mature individuals had a stronger tendency towards awareness of consequences due to personal values; the young had a stronger tendency towards personal norms due to awareness of consequences; men had a stronger tendency towards personal norms due to awareness of consequences; and women had a weaker tendency due to a greater emphasis on altruism. Future interventions, such as sharing of personal pro-environmental lifestyles verbally or through social media, periodically decluttering personal items and maintaining a minimalist lifestyle, where these personal norms are in line with collective social norms, could help to strengthen PEB.

48. A Performance Improvement for Indoor Positioning Systems Using Earth's Magnetic Field.

Author: Yeh SC, Chiu HC, Kao CY, and Wang CH
Abstract: Although most indoor positioning systems use radio waves, such as Wi-Fi, Bluetooth, or RFID, for application in department stores, exhibition halls, stations, and airports, the accuracy of such technology is easily affected by human shadowing and multipath propagation delay. This study combines the earth's magnetic field strength and Wi-Fi signals to obtain the indoor positioning information with high availability. Wi-Fi signals are first used to identify the user's area under several kinds of environment partitioning methods. Then, the signal pattern comparison is used for positioning calculations using the strength change in the earth's magnetic field among the east-west, north-south, and vertical directions at indoor area. Finally, the k-nearest neighbors (KNN) method and fingerprinting algorithm are used to calculate the fine-grained indoor positioning information. The experiment results show that the average positioning error is 0.57 m in 12-area partitioning, which is almost a 90% improvement in relation to that of one area partitioning. This study also considers the positioning error if the device is held at different angles by hand. A rotation matrix is used to convert the magnetic sensor coordinates from a mobile phone related coordinates into the geographic coordinates. The average positioning error is decreased by 68%, compared to the original coordinates in 12-area partitioning with a 30-degree pitch. In the offline procedure, only the northern direction data are used, which is reduced by 75%, to give an average positioning error of 1.38 m. If the number of reference points is collected every 2 m for reducing 50% of the database requirement, the average positioning error is 1.77 m.

Abstract: Purpose of the Study: The risk of bone fracture is high in patients with chronic kidney disease (CKD), and aggressive treatment to reduce fragility fracture risk is the major strategy. However, the outcomes of osteoporosis medications in patients with CKD remain unclear., Study Design: Patients with stage 3-5 CKD during 2011-2019 were enrolled. Patients were divided into two groups based on receiving osteoporosis medications (bisphosphonates, raloxifene, teriparatide or denosumab) or not. Two groups were matched at a 1:1 ratio by using propensity scores. The outcomes of interest were bone fractures, cardiovascular (CV) events and all-cause mortality. Cox proportional hazard regression models were applied to identify the risk factors. Additional stratified analyses by cumulative dose, treatment length and menopause condition were performed., Results and Conclusions: 67 650 patients were included. After propensity score matching, 1654 patients were included in the study and control group, respectively. The mean age was 70.2±12.4 years, and 32.0% of patients were men. After a mean follow-up of 3.9 years, the incidence rates of bone fracture, CV events and all-cause mortality were 2.0, 1.7 and 6.5 per 1000 person-months, respectively. Multivariate analysis results showed that osteoporosis medications reduced the risk of CV events (HR, 0.35; 95% CI, 0.18 to 0.71; p = 0.004), but did not alleviate the risks of bone fracture (HR, 1.48; 95% CI, 0.73 to 2.98; p = 0.28) and all-cause mortality (HR, 0.93; 95% CI, 0.67 to 1.28; p = 0.65). Stratified analysis showed that bisphosphonates users have most benefits in the reduction of CV events (HR, 0.26; 95% CI, 0.11 to 0.64; p = 0.003). In conclusion, osteoporosis medications did not reduce the risk of bone fractures, or mortality, but improved CV outcomes in patients with CKD., (© The Author(s) 2022.

50. The anti-immune dengue subgenomic flaviviral RNA is present in vesicles in mosquito saliva and is associated with increased infectivity.

Abstract: Mosquito transmission of dengue viruses to humans starts with infection of skin resident cells at the biting site. There is great interest in identifying transmission-enhancing factors in mosquito saliva in order to counteract them. Here we report the discovery of high levels of the anti-immune subgenomic flaviviral RNA (sfRNA) in dengue virus 2-infected mosquito saliva. We established that sfRNA is present in saliva using three different methods: northern blot, RT-qPCR and RNA sequencing. We next show that salivary sfRNA is protected in detergent-sensitive compartments, likely extracellular vesicles. In support of this hypothesis, we visualized viral RNAs in vesicles in mosquito saliva and noted a marked enrichment of signal from 3'UTR sequences, which is consistent with the presence of sfRNA. Furthermore, we show that incubation with mosquito saliva containing higher sfRNA levels results in higher virus infectivity in a human hepatoma cell line and human primary dermal fibroblasts. Transfection of 3'UTR RNA prior to DENV2 infection inhibited type I and III interferon induction and signaling, and enhanced viral replication. Therefore, we posit that sfRNA present in salivary extracellular vesicles is delivered to cells at the biting site to inhibit innate immunity and enhance dengue virus transmission., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Yeh et al.
