Abstract

Background: A gemcitabine-cisplatin combination is a standard treatment option for patients with advanced biliary tract carcinoma (BTC). We assessed the efficacy and safety of this regimen at Chang Gung Memorial Hospital. Methods: Between April 2009 and December 2010, 30 chemotherapy-naοve patients (13 men and 17 women; median age: 61.5 years) with advanced BTC were retrospectively analyzed. Treatment consisted of gemcitabine (Gemmis®; TTY, Taipei, Taiwan) 1000 mg/m2, followed by cisplatin 30 mg/m2 on days 1 and 8 every 3 weeks. Tumor response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria every 2-3 cycles. The toxicity was assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 3. Results: At the end of July, 2011, 27 patients were evaluated using the RECIST criteria. According to the intent to treat analysis of response, 5 patients (16.7%) had a partial response, 10 patients (33.3%) had stable disease and 12 patients (40.0%) had progressive disease. The median time to progression (TTP) and median overall survival (OS) of the 30 patients were 4.8 months and 13.4 months, respectively. The patients with biliary obstruction requiring drainage before treatment had a significantly shorter OS than those without biliary obstruction (p = 0.02) even though the TTP showed no statistically significant difference (p = 0.69) between groups. The major grade III/IV adverse events in the 30 patients included infection (n = 8, 26.7%), anemia (n = 5, 16.7%), neutropenia (n = 4, 13.3%), and elevated alanine aminotransferase (n = 2, 6.7%). There were no treatment-related deaths. Conclusions: Gemcitabine plus cisplatin is a feasible chemotherapy regimen with manageable toxicity in patients with advanced BTC. Maintaining good biliary drainage is essential for these patients.

106. THE LIMITS OF GLOBAL JUDICIAL DIALOGUE.

Abstract

The notion that "global judicial dialogue" is contributing to the globalization of constitutional law has attracted considerable attention. Various scholars have characterized the citation of foreign law by constitutional courts as a form of "dialogue" that both reflects and fosters the emergence of a common global enterprise of constitutional adjudication. It has also been claimed that an increasing amount of direct interaction between judges, face-to-face or otherwise, fuels the growth of a global constitutional jurisprudence. This Article challenges these claims on empirical grounds and offers an alternative account of the actual reasons for which constitutional courts engage in comparative analysis. First, it is both conceptually and factually inaccurate to characterize the manner in which constitutional courts cite and analyze foreign jurisprudence as a form of "dialogue." Second, judicial interaction is neither a necessary nor a sufficient cause of constitutional globalization. Rather, the impact of such interaction on the extent to which judges engage in comparativism is dwarfed by institutional and structural variables that lie largely beyond judicial control. The basis of our empirical argument concerning the effects of judicial interaction and reasons for judicial comparativism is a comparative case study of the Constitutional Court of the Republic of China (Taiwan), which is akin to a natural experiment in the capacity of a constitutional court to make use of foreign law even when it is largely deprived of contact with other courts. Taiwan's precarious diplomatic situation ensures that the members of its Constitutional Court are effectively precluded from participating in international judicial gatherings or visits to foreign courts. Nevertheless, Taiwan's Constitutional Court nearly always engages in extensive comparative constitutional analysis, either expressly or implicitly, when rendering its decisions. To explain how and why the Court makes use of foreign law notwithstanding its isolation, we combine quantitative analysis of citations to foreign law in the Court's published opinions with indepth interviews of numerous current and former members of the Court and their clerks. We conclude that "global judicial dialogue" plays a much smaller role in shaping a court's utilization of foreign law than institutional factors such as (a) the rules and practices governing the composition and staffing of the court and (b) the extent to which the structure of legal education and the legal profession incentivizes judges and academics to possess expertise in foreign law. Our conclusion that institutional factors outweigh judicial dialogue in determining a court's reliance on foreign law helps to explain the behavior of not only the Taiwanese Constitutional Court, but also the United States Supreme Court. Notwithstanding the fact that American justices enjoy unsurpassed opportunities to interact with judges from other countries, comparative analysis plays a less frequent role in their own constitutional jurisprudence than in that of their foreign counterparts. Openness on the part of individual justices to foreign law ultimately cannot compensate for the fact that the hiring and instructional practices of American law schools neither demand nor reward the possession of foreign legal expertise. Our research also demonstrates that judicial opinions are a highly misleading source of data about judicial usage of foreign law. As our interviews with members of the Taiwanese Constitutional Court reveal, the frequency with which a court cites foreign law in its opinions does not necessarily reflect the extent to which it actually considers foreign law. Analysis of judicial opinions alone may lead scholars to conclude mistakenly that a court rarely engages in comparative analysis when, in fact, such analysis is highly routine.

Abstract

The HERMES Collaboration recently reported a reevaluation of the strange-quark parton distribution, S(x), based on kaon production in semi-inclusive deep-inelastic scattering. Two distinct results on S(x) at the x > 0.1 region, one with a sizable magnitude and another with a vanishing content, were reported. We show that the latter result is due to a particular assumption adopted in the analysis. The impact of the new HERMES S(x) result on the extraction of intrinsic light-quark sea in the proton is discussed. Given the large uncertainty in the kaon fragmentation function, we find that the latest HERMES data do not exclude the existence of a significant intrinsic strange-quark sea in the proton. The x dependence of the (s + ...)/(ū + ...) ratio is also in qualitative agreement with the presence of intrinsic strange-quark sea. [ABSTRACT FROM AUTHOR]

Abstract

Dystonia is a rare manifestation of multiple sclerosis (MS), but it always interferes with the functional performance and quality of life. We report a rare case of long-lasting paroxysmal dystonia associated with MS. The patient was a 40-year-old woman with relapsing- remitting MS for 6 years. During the latest attack of MS, she suffered from long-lasting paroxysmal dystonia in her left hand. Despite treatment with pulse high-dose intravenous methylprednisolone, interferon, and baclofen, along with occupational therapy, the dystonia persisted and significantly bothered her daily activities. Finally, she was treated with oral acetazolamide (250 mg, three times a day for 4 days), which was very effective for the control of her dystonia. The dystonic movement subsided without recurrence in a follow-up of 17 months. We advocate this effective and safe treatment for patients with paroxysmal dystonia associated with MS.

Abstract

The lepton angular distribution coefficients Ai for Z boson production in pp and pp collisions have been measured at the LHC and the Tevatron. A recent study showed that many features of the measured angular distribution coefficients, including the transverse momentum (qT) and rapidity dependencies and the violation of the Lam-Tung relation, can be well described using an intuitive geometric approach. In this paper, we extend this geometric approach to describe the angular distribution coefficients for W boson produced in pp collisions at the Tevatron. We first compare the data with a perturbative QCD calculation at O(αs²). We then show that the data and QCD calculations can be well described with the geometric approach. Implications for future studies at the LHC energy are also discussed. [ABSTRACT FROM AUTHOR]

Abstract

The gluon distributions of the pion obtained from various global fits exhibit large variations among them. Within the framework of the color evaporation model, we show that the existing pion-induced J/ψ production data, usually not included in the global fits, can impose useful additional constraints on the pion parton distribution functions (PDFs). In particular, these data can probe the pion's gluon densities at large x. Existing pion-induced J/ψ data covering a broad range of beam momenta are compared with next-to-leading-order QCD calculations using various sets of pion PDFs. It is found that J/ψ data measured at forward rapidity and at sufficiently high beam momentum are sensitive to the large-x gluon distribution of pions. The current J/ψ data favor the Sutton-Martin-Roberts-Stirling and Gluck-Reya-Vogt pion PDFs, containing significant gluon content at large x. [ABSTRACT FROM AUTHOR]

119. Mixed Constitutions in East Asia: South Korea and Taiwan as Examples

Abstract

The study of illiberal constitutions has recently generated enormous scholarly interests. Few, however, have focused on whether democracies may still embrace constitutionalism mixed with illiberal elements. This article explores mixed constitutions of South Korea and Taiwan, the two democracies with vibrant civil societies in East Asia. Three distinctive features in both constitutions have demonstrated illiberal elements, including duty clauses imposed upon citizens, directives requiring the State to enact laws to fulfill the goals of governance, and constitutional cultures that exhibit high deference to political elites based on the Confucian tradition. This article further examines the impacts of such mixed constitutions on three challenging issues: managing pandemic crisis, applying artificial intelligence, and combating fake news. This article finds mixed features of illiberal and democratic constitutions in the two countries by giving their governments more space in managing urgent crises, showing higher deference to experts who are generally trusted by the public, and making compromises to individual rights for greater public good. However, this does not imply that the government is not made democratically accountable, or rights and freedoms are not asserted or valued by individuals. To the contrary, nongovernmental organizations and courts in the two countries continue to act as a counterbalancing force, challenging the government’s policies and decisions if not reasonably balanced, weakening the tendency of power concentration that has been seen in other countries where democratic backsliding or authoritarian governance is gradually revived.

Abstract

J-PARC E16 is an experiment to examine the origin of hadron mass through a systematic measurement of spectral changes of vector mesons in nuclei. The measurement of $e^{+}e^{-}$ pairs from the decay of vector mesons will provide the information of the partial restoration of the chiral symmetry in a normal nuclear density. To resolve a pulse pile-up and achieve good discrimination of $e^{\pm}$ from the background of a reaction rate of an order of 10 MHz, the data acquisition (DAQ) system uses waveform sampling chips of APV25 and DRS4. The trigger rate and data rate are expected to be 1 kHz and 130--330 MiB/s, respectively. The DAQ system for readout of APV25 and DRS4 were developed, where events were synchronized by common trigger and tag data. The first commissioning in beam, called Run-0a, was performed in June 2020 with about 1/4 of the designed setup. The DAQ worked with a trigger rate of 300 Hz in the Run-0a and the main bottleneck was a large data size of APV25. Further optimization of the DAQ system will improve the performance., IEEE Real Time 2020 Conference, 4 pages, 6 figures

Abstract

The EIC Comprehensive Chromodynamics Experiment (ECCE) detector has been designed to address the full scope of the proposed Electron Ion Collider (EIC) physics program as presented by the National Academy of Science and provide a deeper understanding of the quark-gluon structure of matter. To accomplish this, the ECCE detector offers nearly acceptance and energy coverage along with excellent tracking and particle identification. The ECCE detector was designed to be built within the budget envelope set out by the EIC project while simultaneously managing cost and schedule risks. This detector concept has been selected to be the basis for the EIC project detector., Comment: 32 pages, 29 figures, 9 tables

126. Lepton angular distributions of fixed-target Drell-Yan experiments in perturbative QCD and a geometric approach.

Abstract

The lepton angular distributions of the Drell-Yan process in fixed-target experiments are investigated by NLO and NNLO perturbative QCD. We present the calculated angular parameters λ, μ, ν and the degree of violation of the Lam-Tung relation, 1 - λ - 2ν, for the NA10, E615 and E866 experiments. Predictions for the ongoing COMPASS and SeaQuest experiments are also presented. The transverse momentum (qT) distributions of λ and ν show a clear dependence on the dimuon mass (Q) while those of μ have a strong rapidity (xF) dependence. Furthermore, λ and ν are found to scale with qT/Q. These salient features could be qualitatively understood by a geometric approach where the lepton angular distribution parameters are expressed in terms of the polar and azimuthal angles of the "natural axis" in the dilepton rest frame.

Abstract

High precision data of lepton angular distributions for γ*/Z production in pp collisions at the LHC, covering broad ranges of dilepton transverse momenta (qT) and rapidity (y), were recently reported. Strong qT dependencies were observed for several angular distribution coefficients, Ai, including A0-A4. Significant y dependencies were also found for the coefficients A1, A3 and A4, while A0 and A2 exhibit very weak rapidity dependence. Using an intuitive geometric picture, we show that the qT and y dependencies of the angular distributions coefficients can be well described. [ABSTRACT FROM AUTHOR]

129. East Asian Foundations for Constitutionalism: Resistance or Reconstruction?

Abstract

The majority of countries in East Asia have become liberal democracies with vibrant developments of constitutionalism and rule of law. Scant attention, however, has been paid to particular social, political and cultural foundations for East Asian constitutionalism. Worse, constitutionalism in East Asia has been attributed merely to the global expansion of constitutionalism from the West. Without a formal recognition of constitutionalism in East Asia, the discourse of constitutionalism loses the opportunity to understand diverse ways of constructing and reconstructing constitutionalism. This paper, as part of a larger research project on East Asian constitutionalism, proposes to utilize the approach of constitutional ethnography to examine the founding, destruction and transformation of constitutional rules in Japan, South Korea and Taiwan. By examining social, political and cultural circumstances in which these leading constitutional democracies in East Asia established their respective constitutional regimes, this paper seeks to argue that a distinctive life of constitutionalism has been brought to birth in East Asia. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Abstract

Background: This prospective phase II clinical trial evaluated the efficacy and toxicity of cisplatin, oral tegafur-uracil, leucovorin, and mitomycin C in patients with recurrent or metastatic nasopharyngeal carcinoma. Methods: Patients with histologically proven non-keratinizing or undifferentiated nasopharyngeal carcinoma were prospectively enrolled from April 2002 to June 2005. Cisplatin 50 mg/m 2 on day 1, 22 and mitomycin C 6 mg/m 2 on day 1 were administered. Oral tegafur-uracil 300 mg/m 2 /day and oral leucovorin 60 mg/day were given on day 1-14 and day 22-35, respectively. Each cycle was repeated every 6 weeks. Primary and secondary endpoints are response rate and toxic profiles with survivals, respectively. Results: Twenty-two patients with the median age of 47 (35-69) years were enrolled in the study. Sixteen (72.7%) patients had undifferentiated nasopharyngeal carcinoma. The regimen was well-tolerated by all patients with the exception of one patient (4.6%) who experienced grade IV anorexia, and two patients (9.1%) who had grade IV vomiting. There was no treatment-related death. The overall response rate was 59.1%, including 3 (13.6%) complete remissions. The median duration of response was 15.9 months, the median time to tumor progression was 10.0 months, and the median overall survival was 16.0 months. Conclusion: This outpatient chemotherapy regimen is acceptably effective and toxic among patients with recurrent or metastatic nasopharyngeal carcinoma.
