First Observation of Λπ^{+} and Λπ^{-} Signals near the K[over ¯]N(I=1) Mass Threshold in Λ_{c}^{+}→Λπ^{+}π^{+}π^{-} Decay. PHYSICAL REVIEW LETTERS 2023; 130:151903.

Abstract
Using the data sample of 980 fb^{-1} collected with the Belle detector operating at the KEKB asymmetric-energy e^{+}e^{-} collider, we present the results of an investigation of the Λπ^{+} and Λπ^{-} invariant mass distributions looking for substructure in the decay Λ_{c}^{+}→Λπ^{+}π^{+}π^{-}. We find a significant signal in each mass distribution. When interpreted as resonances, we find for the Λπ^{+} (Λπ^{-}) combination a mass of 1434.3±0.6(stat)±0.9(syst) MeV/c^{2} [1438.5±0.9(stat)±2.5(syst) MeV/c^{2}], an intrinsic width of 11.5±2.8(stat)±5.3(syst) MeV/c^{2} [33.0±7.5(stat)±23.6(syst) MeV/c^{2}] with a significance of 7.5σ (6.2σ). As these two signals are very close to the K[over ¯]N threshold, we also investigate the possibility of a K[over ¯]N cusp, and find that we cannot discriminate between these two interpretations due to the limited size of the data sample.

Abstract
Study question
Could autologous adipose stem cell (ASC) mitochondria supplementation restore the post-fertilization development potentialin vitrified-thawed oocytes?
Summary answer
Autologous ASC mitochondria supplementation could rejuvenate the quality of vitrified-thawed oocytes and enhance the embryo’s developmental capacity.
What is known already
Pre- and post-implantation developmental potential of embryos derived from vitrified oocytes are remarkedly lower than those of fresh oocytes. Despite its’ low efficacy, oocyte cryopreservation is becoming prevalent in assisted reproductive technologies to cater the growing demands due to patients' sociological and pathological conditions. Unfavorable effects to mitochondrial membrane potential, mitochondrial structure, ATP production, reactive oxygen species (ROS), meiotic spindle and microfilaments, and Ca2+ ion regulation are reported as detrimental damages in oocytes following the cryopreservation, that adversely affect the development potential. Furthermore, autologous stem cell mitochondria supplementation can rescue the aging-related oocyte mitochondrial damages.
Study design, size, duration
The mature oocytes, autologous ASC, and mitochondria were collected from young mice and analyzed at Osaka City University, Japan. In total, 600 young mouse mature oocytes were occupied in this prospective study.
Participants/materials, setting, methods
Young C57BL/6JJmsmouse (8weeks) mature oocytes that have been pre-vitrified were thawed before the start of the ICSI procedure.ASC specificity and ASC mitochondria function and ultrastructure were pre-analyzed. ASC mitochondria were isolated on the same day and supplemented with intracellular sperm injection (ICSI) and as the control, the mitochondrial buffer was injected. The survival rate, fertilization rate, blastulation, mitochondria function, ROS level in 2 cell embryos, and live birth rates were compared between the 2 groups.
Main results and the role of chance
The ASC mitochondriashowed higher membrane potential compared to the somatic cells and were spherical in shape with low cristae numbers. The survival rate and the fertilization ratewere comparable in both mitochondria supplemented and control groups. However, theASC mitochondria supplementation seemed to havesignificantly improvedthe blastocyst development capacity from 2cell embryos compared to the control group (P < 0.05;56.8% & 38.2%, respectively).And interestingly, a significantly higher ATP level was found in the mitochondria supplemented group’s 2 cell embryos thanin the control group (P < 0.05;905.6pmol & 561.1pmol respectively). And though it was not statistically significant, a higher potential ofgetting live birth was found in the mitochondria supplemented group thanthe control group after 2 cell embryo transfer.
Limitations, reasons for caution
We acknowledge that the absence of compared data with fresh oocytes’ ICSI, the detailed cellular mechanism behind theimprovement of embryo development, and transgenerational safety in offspring developed fromthe mitochondria supplementation werethe limitations of this study.
Wider implications of the findings
With these results, we propose that ASC mitochondria supplementation could rejuvenate the quality of cryopreserved oocytes and enhance the embryo developmental capacity, signifying another possible approach of mitochondrial transplantation therapy.

Abstract
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ→vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community.

Abstract
We have developed a denoising autoencoder based neural network (NN) method to determine a spectral line intensity with an uncertainty lower than the uncertainty determined by fitting the spectral line. The NN method processes the measured raw spectral line shape, providing a single Gaussian shape based on the training dataset, which consists of synthetically prepared Doppler shift and broadening free spectral lines in the present work. It is found that the uncertainty reduction level significantly depends on the training dataset. Limitations originating from the training dataset are also discussed.

Abstract
Abstract
Background
Peri-stent contrast staining (PSS) has been reported to be associated with very late stent thrombosis.
The aims of this study was to compare the occurrence rate of PSS between second generation drug-eluting stents (2nd DES) and third generation drug-eluting stents (3rd DES), and to identify clinical characteristics associated with PSS.
Methods and results
This study comprised 1899 patients with 2493 de novo lesions treated with 2nd or 3rd DES from October 2015 to September 2018. Follow-up angiography was available for 1883 lesions (75.5%). There were 725 patients with 968 lesions treated with 2nd DES, and 716 patients with 915 lesions treated with 3rd DES. The occurrence of PSS, types of PSS, and VLST related to PSS were compared between 2nd and 3rd DES implantation. Mean follow-up period was 30±12 months. The occurrence rate of PSS and segmental type of PSS were similar between two groups (2nd DES vs. 3rd DES, 1.5% vs. 1.7%, p=0.73, 47% vs. 50%, p=0.85, and respectively). The VLST related to PSS occurred in only one case in 3rd DES group. (0% vs. 6.3%, p=0.33).
Conclusion
The occurrence rate of PSS and clinical course were similar between 2nd and 3rd DES.

Abstract
Patients with advanced salivary gland mucoepidermoid carcinoma (MEC) are treated with surgery and radiotherapy, as current systemic therapies are largely ineffective. As such, current treatment frequently leads to poor long-term survival due to locoregional recurrence or metastases. We have shown that salivary gland cancer stem cells (CSCs) are resistant to platinum-based chemotherapy and drive tumor progression. The purpose of this study was to investigate the effect of therapeutic inhibition of mTOR (mechanistic target of rapamycin) on resistance of CSCs to cisplatin, a prototypic platinum-based chemotherapeutic agent. Viability assays determined the effect of several inhibitors of PI3k/mTOR signaling (e.g., temsirolimus, BKM120, AZD8055, PF4708671) and/or cisplatin on survival of human MEC cells. The impact of mTOR inhibitors and/or cisplatin on MEC stemness was examined with salisphere assays, flow cytometry for ALDH/CD44 (CSC markers for MEC), and Western blots for Bmi-1 expression (marker of stem cell self-renewal). Salivary gland MEC patient-derived xenografts were used to examine the effect of cisplatin and/or temsirolimus on CSCs in vivo. We observed that cisplatin induced mTOR and S6K1 phosphorylation, increased the number and size of MEC salispheres, and induced Bmi-1 expression and the fraction of CSCs in MEC models in vitro. Cisplatin also increased the fraction of CSCs in vivo. In contrast, mTOR inhibition (e.g., temsirolimus) blocked cisplatin-induced Bmi-1 expression and salisphere formation in vitro. Remarkably, temsirolimus slowed down tumor growth and decreased the fraction of CSCs (P < 0.05) even in presence of cisplatin in a short-term in vivo experiment. Collectively, these results demonstrate that therapeutic inhibition of mTOR ablates cytotoxic-resistant CSCs, and they suggest that a combination of an mTOR inhibitor and platinum-based chemotherapy might be beneficial to patients with salivary gland mucoepidermoid carcinoma.

Abstract
We measured missing mass spectrum of the ^{12}C(γ,p) reaction for the first time in coincidence with potential decay products from η^{'} bound nuclei. We tagged an (η+p) pair associated with the η^{'}N→ηN process in a nucleus. After applying kinematical selections to reduce backgrounds, no signal events were observed in the bound-state region. An upper limit of the signal cross section in the opening angle cosθ_{lab}^{ηp}<-0.9 was obtained to be 2.2 nb/sr at the 90% confidence level. It is compared with theoretical cross sections, whose normalization ambiguity is suppressed by measuring a quasifree η^{'} production rate. Our results indicate a small branching fraction of the η^{'}N→ηN process and/or a shallow η^{'}-nucleus potential.

Abstract
We report the first observation of the radiative decay of the ϒ(1S) into a charmonium state. The significance of the observed signal of ϒ(1S)→γχ_{c1} is 6.3 standard deviations including systematics. The branching fraction is calculated to be B[ϒ(1S)→γχ_{c1}]=[4.7_{-1.8}^{+2.4}(stat)_{-0.5}^{+0.4}(sys)×10^{-5}]. We also searched for ϒ(1S) radiative decays into χ_{c0,2} and η_{c}(1S,2S), and set upper limits on their branching fractions. These results are obtained from a 24.9 fb^{-1} data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider at a center-of-mass energy equal to the ϒ(2S) mass using ϒ(1S) tagging by the ϒ(2S)→ϒ(1S)π^{+}π^{-} transitions.

Abstract
UNLABELLED A 48-week, multicenter, randomized, double-blind, double-dummy, active-controlled, non-inferiority trial (the TWICE study) conducted in Japanese primary osteoporosis patients with a high risk of fractures demonstrated that a 28.2-μg twice-weekly regimen of teriparatide can provide comparable efficacy to a 56.5-μg once-weekly regimen of teriparatide, while also improving safety. INTRODUCTION While a 56.5-μg once-weekly regimen of teriparatide has high efficacy for osteoporosis, treatment continuation rates are low, with one of the major causes being adverse drug reactions such as nausea or vomiting. The TWICE study was therefore conducted to investigate whether a twice-weekly regimen with 28.2-μg teriparatide can provide comparable efficacy to the 56.5-μg once-weekly regimen while improving safety. METHODS A 48-week, multicenter, randomized, double-blind, double-dummy, active-controlled, non-inferiority trial was conducted in Japan. Patients with primary osteoporosis aged ≥ 65 years at high risk of fractures (n = 553) were randomly allocated to the 28.2-μg twice-weekly group (n = 277) or the 56.5-μg once-weekly group (n = 276). The primary endpoint was the percentage change in lumbar spine (L2-L4) bone mineral density (BMD) at final follow-up. RESULTS The percentage changes in lumbar spine (L2-L4) BMD at final follow-up in the 28.2-μg twice-weekly and 56.5-μg once-weekly groups were 7.3% and 5.9%, respectively; the difference (95% confidence interval [CI]) in percentage change was 1.3% (0.400-2.283%). Since the lower limit of the 95% CI was above the pre-specified non-inferiority margin (- 1.6%), non-inferiority of the 28.2-μg twice-weekly group was demonstrated. Adverse drug reactions were significantly less frequent in the 28.2-μg twice-weekly group (39.7% vs 56.2%; p < 0.01); the incidence of major adverse drug reactions was lower, and the number of subjects who discontinued due to adverse drug reactions was less in the 28.2-μg twice-weekly group. CONCLUSIONS A 28.2-μg twice-weekly regimen of teriparatide can provide comparable efficacy to a 56.5-μg once-weekly regimen while improving safety. CLINICAL TRIAL REGISTRATION JapicCTI-163477 .

Abstract
Abstract
Background
Currently, cryoballoon ablation (CBA) has proven to be highly effective in achieving free from atrial fibrillation (AF), especially paroxysmal AF. However, the optimal freezing protocol for each patient to achieve successful pulmonary vein isolation by only CBA is still uncertain. The aim of this study was to evaluate the clinical implications of a reduction in the freezing duration (<180s) during CBA guided by the time to target temperature.
Methods
From November 2015 to August 2018, 286 consecutive paroxysmal AF patients undergoing CBA were enrolled. We compared 107 patients undergoing a tailor-made CBA procedure (Group A; August 2017-August 2018) to 179 patients with a standard CBA procedure (Group B; November 2015–July 2017). In Group A, the freezing duration was reduced to 150s when the temperature reached ≤−40°C within 40s. Furthermore, we reduced it to 120s when it reached ≤−50°C within 60s. In the other patients, the freezing time was 180s except for excessive freezing over −60°C and/or emergent situations while monitoring the esophageal temperature and for phrenic nerve injury as in Group B.
Results
The baseline clinical characteristics were similar between two groups. In Group A, 89 patients (83%) underwent CBA with a reduction in the freezing time. The rate of having reduction time in left inferior PV (LIPV) and right inferior PV (RIPV) was lower compared with left superior PV (LSPV) and right superior PV (RSPV) (respectively 17%, 29%, 56%, and 63.5%). However, for right inferior PV, in 31 patients having the reduced freezing time, none of them required touch-up ablation. Although the procedure time and frequency of touch-up ablation did not differ between the 2 groups, total freezing time for each PV was significantly shorter in Group A than Group B as shown in figure (LSPV: 164±28s vs. 216±67s; p<0.001, LIPV: 187±44s vs. 218±69s; p<0.001, RSPV: 147±31s vs. 192±51s; p<0.001, RIPV: 180±50 vs. 218±73s; p<0.001). The AF free survival rate during the follow-up period (356±167 days) was similar between the 2 groups (log-rank test, p=0.38). Furthermore, the complication rate was similar 2 groups.
The freezing time for each PV
Conclusion
The safety and efficacy of the new tailor-made CBA strategy were non-inferior to the standard procedure. This study showed that the unnecessary freezing time could be reduced in most of paroxysmal AF patients.

Abstract
Abstract
Background
Drug-eluting stent restenosis (DES-ISR) is associated with poorer outcomes than those of bare-metal stent restenosis after treatment with paclitaxel-coated balloon (PCB), and late restenosis after PCB angioplasty for DES-ISR is a residual problem. Excimer laser coronary angioplasty (ELCA) is thought to be advantageous for ISR treatment by removing neointima. However, whether the combination of ELCA and PCB angioplasty is more effective than the use of PCB only angioplasty in DES-ISR has not been studied so far.
Purpose
We evaluated the efficacy of ELCA and PCB combination therapy for DES-ISR at mid-and late-term after revascularization.
Methods
From January 2014 to March 2016, 166 DES-ISR lesions were treated with ELCA and no-ELCA prior to PCB. Two serial angiographic follow-ups were planned for the patients (at 6–12 and 18–24 months after procedure). Acute procedural and follow-up angiographic results were assessed by quantitative coronary angiography. ELCA and no-ELCA group included 74 lesions and 92 lesions, respectively.
Results
There was no significant difference between the two groups in the clinical characteristics except the prevalence of hemodialysis, the rate of first-generation DES (37.9% vs 36.8%, p=0.897), previous stent size (2.90±0.39 mm vs 2.77±0.39 mm, p=0.063), and reference vessel diameter (2.65±0.46 mm vs 2.60±0.65 mm, p=0.593). Early follow-up angiography was performed in 66 lesions (89.1%) of ELCA group, and was done in 76 lesions (82.6%) of no-ELCA group. In the ELCA group, percentage diameter stenosis (%DS) just after procedure and at 6–12 months later were significantly smaller than those of no-ELCA group. Besides, target lesion revascularization (TLR) rate at 6–12 months after procedure was tended to be lower in the ELCA group. Late follow-up angiography was performed for 93 lesions (81.6%) of the remaining 114 lesions (excluding TLR lesion), late restenosis was found 9 lesions (18.6%) in the ELCA group and 11 lesions (24.4%) in the no-ELCA group (p=0.504). Late luminal loss was similar in both groups (0.37±0.71 mm vs 0.24±0.82 mm, p=0.438), and %DS at 12–18 months after revascularization was not different between the two groups.
Changes of %DS and TLR rate
Conclusions
%DS in the ELCA group was smaller at just after procedure and the advantage was kept even after 1-year. However, late restenosis and TLR at 2-year after revascularization for DES-ISR could not be reduced by ELCA and PCB combination therapy.

Tongue surface model can predict radiation tongue mucositis due to intensity-modulated radiation therapy for head and neck cancer. Int J Oral Maxillofac Surg 2019; 49:44-50.

Abstract
Acute radiation tongue mucositis has a profound effect on talking and eating. We examined whether the dose-volume histogram obtained from the tongue surface model correlates with mucositis severity, and whether it is useful for predicting acute radiation tongue mucositis in patients with head and neck cancer treated with intensity-modulated radiation therapy. Thirty-six patients who received intensity-modulated radiation therapy for head and neck cancer were analysed for acute radiation tongue mucositis according to the Common Terminology Criteria for Adverse Events, version 4.0, as well as the Radiation Therapy Oncology Group scoring systems. The corresponding high-dose locations in anatomical sub-regions in the tongue surface model and the development of high-grade acute radiation tongue mucositis were compared. The mucositis sites coincided with the high-dose anatomical sub-regions in the tongue surface model. There was a clear dose-response relationship between the mean dose to the tongue and the acute radiation tongue mucositis Radiation Therapy Oncology Group grade. According to the dose-volume histogram, patients receiving 16.0-73.0 Gy to the tongue were susceptible to grade 2-3 toxicity. The tongue surface model can predict the site and severity of acute radiation tongue mucositis. In future, radiation treatment plans ccould be optimized using this model.

Abstract
Neoadjuvant chemotherapy (NAC) is administered to many patients with esophageal squamous cell carcinoma (ESCC) prior to surgery, but it is also true that some of these patients demonstrated no response to the therapy following surgery. In addition, the prognosis of advanced case such as ESCC patients with lymph node metastasis has remained relatively low. Programmed death ligand-1 (PD-L1) in conjunction with tumor-infiltrating lymphocytes (TILs) has been studied as a potential mechanism of "immune escape" in several human malignancies. Therefore, in this study, we studied PD-L1 status in carcinoma cells and forkhead box protein 3 (FOXP3) and CD8 status among TILs in the residual tumors of primary and metastatic sites following NAC. We also studied the association of these factors with the clinicopathological findings in 44 patients with ESCC harboring lymph node metastasis. There was discordance in the pathological response to chemotherapy between the primary tumor and lymph node metastasis, and histologically identified resistance to NAC in lymph node metastases tended to be correlated with an adverse clinical outcome (P = 0.0765) than resistance in the primary tumor. Both univariate and multivariate analyses for disease-specific survival (DSS) revealed that the PD-L1 status of carcinoma cells in metastatic lymph nodes and a higher FOXP3/CD8 ratio in the primary tumor were both significantly correlated with an eventual adverse clinical outcome of the patients (P = 0.0178, P = 0.0463, respectively). These results all indicated that the PD-L1 status of carcinoma cells in metastatic lymph nodes and the FOXP3/CD8 ratio in primary tumors could predict eventual clinical outcomes in ESCC patients with NAC.

Abstract
We report the first observation of the double strange baryon Ξ(1620)^{0} in its decay to Ξ^{-}π^{+} via Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+} decays based on a 980 fb^{-1} data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The mass and width are measured to be 1610.4±6.0(stat)_{-4.2}^{+6.1} (syst) MeV/c^{2} and 59.9±4.8(stat)_{-7.1}^{+2.8}(syst) MeV, respectively. We obtain 4.0σ evidence of the Ξ(1690)^{0} with the same data sample. These results shed light on the structure of hyperon resonances with strangeness S=-2.

Thoracoscopic Esophagectomy for a Patient With Perforated Esophageal Epiphrenic Diverticulum After Kidney Transplantation: A Case Report. Transplant Proc 2018; 50:3964-3967.

Abstract
A 58-year-old man who underwent cadaveric kidney transplantation twice presented to hospital with a perforated epiphrenic diverticulum. Computed tomography revealed epiphrenic diverticulitis and right pleural effusion. Upper gastrointestinal fibroscopy showed an epiphrenic diverticulum full of food residue. He was transferred to our hospital, where we performed percutaneous endoscopic gastrostomy under general anesthesia in the supine position before thoracoscopy. Thoracoscopic esophagectomy was performed in the semi-prone position under 6-10 mmHg artificial pneumothorax via the right thoracic cavity. We performed subtotal esophagectomy to remove sources of infection because the esophageal wall surrounding the diverticulum was too thick to close or to perform diverticulectomy. A cervical esophagostomy was constructed after the thoracic procedure. The patient was managed with continuous hemodiafiltration and administered immunosuppressants and steroids to preserve the transplanted kidney. Continuous hemodiafiltration was stopped on postoperative day (POD) 4. The patient was discharged from the intensive care unit on POD 10 and transferred to the original hospital on POD 24 for rehabilitation. The second operative stage was performed on POD 157 at our hospital. We performed gastric tube reconstruction via the ante-sternal route and anastomosed the tube to the cervical esophagus. The postoperative course was uneventful; the patient was transferred to the original hospital on POD 15 after the second operation. Minimally invasive surgery was sufficient to treat perforated epiphrenic diverticulum while preserving the transplanted kidney. We recommend completely removing the source of infection and reducing surgical invasiveness to preserve the transplanted kidney in cases of esophageal perforation following kidney transplantation.

Abstract
OBJECTIVE The objective of this study was to evaluate the effects of earlier intervention by an antimicrobial stewardship team (AST) on antimicrobial use, antimicrobial resistance rates, and the clinical outcomes, without changing the weekly intervention schedule. METHODS A retrospective study was conducted at Fukuoka University Hospital between April 2013 and March 2016. The effects were compared among three study periods (SP): SP1 (patients receiving anti-methicillin-resistant Staphylococcus aureus agents and carbapenems for ≥14 days), SP2 (patients receiving specific antimicrobials for ≥14 days), and SP3 (patients receiving specific antimicrobials regardless of the duration of treatment). RESULTS The timing of AST intervention was shortened from an average of 15.5days after administration in SP1 to 4.2 days in SP3. The antimicrobial use density (AUD) of carbapenems and piperacillin-tazobactam decreased significantly (SP2 vs. SP3, p<0.05), and the costs of specific antimicrobials decreased (SP1, US$ 1080000; SP2, US$ 944000; SP3, US$ 763000). The rates of carbapenem resistance among Pseudomonas aeruginosa isolates showed a significant reduction from 16.2% in SP2 to 8.7% in SP3 (p<0.05). The mortality rate and length of stay did not change during the study period. CONCLUSIONS Earlier intervention by an AST could contribute to the proper use of antimicrobials without adversely affecting patient outcomes.

Abstract
The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

Differential Cross Section and Photon-Beam Asymmetry for the γ[over →]p → π^{-}Δ^{++}(1232) Reaction at Forward π^{-} Angles for E_{γ}=1.5-2.95 GeV. PHYSICAL REVIEW LETTERS 2018; 120:202004.

Abstract
Differential cross sections and photon-beam asymmetries for the γ[over →]p→π^{-}Δ^{++}(1232) reaction have been measured for 0.7<cosθ_{π}^{c.m.}<1 and E_{γ}=1.5-2.95 GeV at SPring-8/LEPS. The first-ever high statistics cross-section data are obtained in this kinematical region, and the asymmetry data for 1.5<E_{γ}(GeV)<2.8 are obtained for the first time. This reaction has a unique feature for studying the production mechanisms of a pure uu[over ¯] quark pair in the final state from the proton. Although there is no distinct peak structure in the cross sections, a non-negligible excess over the theoretical predictions is observed at E_{γ}=1.5-1.8 GeV. The asymmetries are found to be negative in most of the present kinematical regions, suggesting the dominance of π exchange in the t channel. The negative asymmetries at forward meson production angles are different from the asymmetries previously measured for the photoproduction reactions producing a dd[over ¯] or an ss[over ¯] quark pair in the final state. Advanced theoretical models introducing nucleon resonances and additional unnatural-parity exchanges are needed to reproduce the present data.

Abstract
Abstract.In field measurements, monitoring of core body temperature is influenced by physical activities; therefore, the estimation of circadian rhythm from the data may not be exact. The purpose of this study is to design a core body temperature filter in order to reduce artifacts induced by physical activities using simultaneously recorded physiological data such as heart rate data.The effects of physical activities on core body temperature and heart rate are assessed through three experiments. Based on the above knowledge, a core body temperature filter was designed. The filter removes part of rectal temperature data as artifact when heart rate rises above a predetermined threshold. As a result, most of the spike-like noise was removed and the filtered temperature data showed sinusoidal variation more than the unfiltered data. The mesor of the estimated rhythm significantly decreased. This filtering method can provide more precise information about circadian rhythm, especially in field measurements.
