Abstract
BACKGROUND Under atmospheric pressure, the identifiable phases of ice crystals are hexagonal (stable) and cubic (metastable). OBJECTIVE This study aimed to test the hypothesis that water crystallizes into the cubic phase at the beginning and then changes to the hexagonal phase. MATERIALS AND METHODS Aqueous solutions of 40% (w/w) and 50% (w/w) glucose, and 40% (w/w) ammonium hydrogen sulfate, as well as emulsified water, were investigated. RESULTS The cubic-to-hexagonal ice phase transition was detected in 40% (w/w) glucose solution within a 1 s integration interval, whereas the cubic ice formed in 50% (w/w) glucose solution did not transition to the hexagonal phase. The cubic phase was also confirmed in the 40% (w/w) ammonium hydrogen sulfate solution, but not in emulsified water. CONCLUSION The cubic-to-hexagonal ice phase transition was detected in three aqueous solutions tested upon freezing. It was not possible to clearly capture the transition process in emulsified water under the study condition.

Abstract
Abstract
Background
Elder abuse is a serious public health concern that increases the risks of negative health outcomes globally. It is well known that abuse in older adults is associated with depression; however, longitudinal studies investigating the causal relationship between these events are scarce. Because the cause precedes the result over time, the temporal relationships between abuse and depression should be verified from each direction. This longitudinal study therefore investigated and clarified whether depression causes or results from elder abuse among older Japanese adults.
Methods
Two longitudinal analyses were conducted using data derived from the Japan Gerontological Evaluation Study. The data were collected in 2010 and 2013 through a mail survey of 1737 people (983 females, 754 males) across Japan.
Results
Of those who did not experience abuse in 2010, 38 (5.0%) males and 53 (5.4%) females newly experienced abuse in 2013. Among respondents who did not have depressive symptoms in 2010, 60 (8.0%) males and 61 (6.2%) females newly reported depressive symptoms in 2013. After adjusting for demographic factors in analysis 1, people who experienced abuse were 2.28-fold (95% confidence interval [CI] = 1.68-3.09) more likely to have depressive symptoms 3 years later than those who were not abused. In analysis 2, respondents who had mild or severe depression in 2010 were 2.23-fold (95% CI = 1.61-3.10) more likely to have experienced abuse after 3 years than those who did not have depression.
Conclusions
After adjusting for several demographic factors, the results showed that abuse can lead to depression and that depression can be a cause of abuse. Therefore, preventing abuse should be considered from both directions.
Key messages
Elder abuse could be a cause for depressive symptoms. Depressive symptoms could be a cause of elder abuse.

Abstract
Abstract
Background
The connection in a local community has diluted in an aging society, and the importance of intergenerational exchange has increased for older adults' health. Some positive effects of intergenerational exchange have reported. For example, a reciprocal intergenerational exchange contributes to better mental health in later life. However, there is little evidence of the relationship between neighborhood environments causing intergenerational exchange and the health status of older adults. This study investigated the association between geographical accessibility to elementary school, enhancing intergenerational exchange, and depression in older adults.
Methods
The data were retrieved from the Japan Gerontological Evaluation Study (JAGES) 2016, a population-based study of independently living people ≥65 years old. The dependent variable is depression evaluated by the Geriatric Depression Scale (GDS≥5). The geographical accessibility to elementary School is the distance between the representative points of their residences and the nearest elementary school. Logistic regression analysis calculates the odds ratio to determine the association between depression and accessibility to elementary school and compare models to examine the effect of intermediate factors.
Results
Overall, 20.4% of the participants had depression. Compared with the longest distance from elementary school (≥950m), the odds ratio was 0.91 (95% CI = 0.86, 0.96) for the nearest category (<330m), 0.91 (95% CI = 0.87, 0.96) for the second-nearest (330-490m) and 0.94 (95% CI = 0.89, 0.99) for the third (490-670m) in model 1. After adjusting for intermediate factors, the odds ratio was 0.94 for the first and second-nearest groups.
Conclusions
Geographical accessibility to elementary school was associated with decreased depression for older adults. The result indicates that older adults' daily meetings with children around elementary schools can result in a positive effect on their mental health.
Key messages
Geographical accessibility to elementary school was associated with decreased depression for older adults. The neighborhood design enhancing intergenerational exchange might be useful for age-friendly cities.

Abstract
Despite their prevalence and burdens, oral diseases are neglected in universal health coverage. In Japan, a 30% copayment (out of pocket) by the user and a 70% contribution by Japan’s universal health insurance (JUHI) are required for dental and medical services. From the age of 70 y, an additional 10% is offered by JUHI (copayment, 20%; JUHI, 80%). This study aimed to investigate the effect of cost on dental service use among older adults under the current JUHI system. A regression discontinuity quasi-experimental method was used to investigate the causal effect of the JUHI discount policy on dental visits based on cross-sectional data. Data were derived from the 2016 Japan Gerontological Evaluation Study. This analysis contained 7,161 participants who used JUHI, were aged 68 to 73 y, and responded to questions regarding past dental visits. Analyses were controlled for age, sex, number of teeth, and equalized household income. Mean ± SD age was 72.1 ± 0.79 y for the discount-eligible group and 68.9 ± 0.78 y for the noneligible group. During the past 12 mo, significantly more discount-eligible participants had visited dental services than noneligible participants (66.0% vs. 62.1% for treatment visits, 57.7% vs. 53.1% for checkups). After controlling for covariates, the effect of discount eligibility was significant on dental treatment visits (odds ratio [OR], 1.36; 95% CI, 1.32 to 1.40) and dental checkups (OR, 1.49; 95% CI, 1.44 to 1.54) in the regression discontinuity analysis. Similar findings were observed in triangular kernel-weighted models (OR, 1.38 [95% CI, 1.34 to 1.44]; OR, 1.52 [95% CI, 1.47 to 1.56], respectively). JUHI copayment discount policy increases oral health service utilization among older Japanese. The price elasticity for dental checkup visits appears to be higher than for dental treatment visits. Hence, reforming the universal health coverage system to improve the affordability of relatively inexpensive preventive care could increase dental service utilization in Japan.

Abstract
Acceleration of particles from the interaction of ultraintense laser pulses up to 5×10^{21} W cm^{-2} with thin foils is investigated experimentally. The electron beam parameters varied with decreasing spot size, not just laser intensity, resulting in reduced temperatures and divergence. In particular, the temperature saturated due to insufficient acceleration length in the tightly focused spot. These dependencies affected the sheath-accelerated protons, which showed poorer spot-size scaling than widely used scaling laws. It is therefore shown that maximizing laser intensity by using very small foci has reducing returns for some applications.

Abstract
The Linear IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) is aiming at demonstrating the low energy section of a 40 MeV/125 mA IFMIF deuteron accelerator up to 9 MeV with a full beam current in cw operation. For such a high-power beam, the LIPAc injector is required to produce a 100 keV D+ beam with 140 mA and match it for injection into the Radio Frequency Quadrupole (RFQ) accelerator. The injector is designed by CEA-Saclay based on the high intensity light ion source (SILHI). In 2019, the commissioning of the RFQ to demonstrate the D+ beam acceleration at a low duty cycle (0.1%) was conducted. A nominal beam current of 125 mA D+ beam was accelerated up to 5 MeV through the RFQ successfully. The LIPAc injector fully satisfied the requirements for RFQ beam commissioning at the pulse mode.

Abstract
Abstract
Background
Childhood maltreatment can have a significant impact on health across the life course, but its impact on health care costs in later life is unknown in Japan. This study aims to assess additional medical costs of Japanese older people with childhood maltreatment history.
Methods
Data from the Japan Gerontological Evaluation Study (JAGES) 2013, a population-based cohort of independent people aged 65 years or older across Japan were used and linked uniquely with the database of health insurance claims for residents of a city with more than 1.5 million citizens, aged 75 years or younger (N = 978). Average annual medical costs for April 2012 and March 2013 and April 2013 and March 2014 were calculated and compared between those who experienced childhood maltreatment and those who did not, using generalized linear models.
Results
4.5% of our sample witnessed their father physically abusing their mother, 1.9% were physically abused, 10.6% were emotionally neglected, and 5.7% were emotionally abused in their childhood. Average medical costs of those with any childhood maltreatment (N = 176, 18.0% of the sample) were significantly higher than those without maltreatment (549,468JPY vs. 413,013JPY (1USD is equivalent to 110JPY); p = 0.007). When examining the effect of each type of maltreatment, average costs of those with emotional neglect were higher than the counterpart (573,481JPY vs. 412,082JPY; p = 0.008). Average costs of those who experienced physical abuse were also higher than those who did not (726,254JPY vs 431,106JPY; p = 0.035). The effect of any childhood maltreatment remained statistically significant after older adults’ age and gender were controlled (p = 0.03).
Conclusions
Our findings suggest that childhood maltreatment is strongly associated with additional medical costs among older Japanese. If it was truly causal, it can be estimated that additional medical costs associated with childhood maltreatment can be more than 333 billion JPY per year nationwide.
Key messages
Average annual medical costs of older adults with any childhood maltreatment history were significantly 116,098 JPY greater than those with no maltreatment history. As for each type of childhood maltreatment, emotional neglect tends to increase medical costs in late adulthood.

Abstract
Abstract
Background
Previous research has linked built environments to physical activity. However, the association between built environments and musculoskeletal pain is unknown. This study aimed to investigate the effects of neighborhood walkability as a built environment on the knee and low back pain for older people.
Methods
Data were from the Japan Gerontological Evaluation Study (JAGES) 2013, a population-based study of independent people from aged 65 and older. A cross-sectional multilevel analysis was performed on 22,892 subjects in 792 neighborhoods. We used neighborhood walkability as regional level residents’ perception of access to parks and sidewalks and fresh food stores and difficulty in walking due to slopes and stairs and population density. Knee and low back pain which restrict daily life within the past year were our objective variables.
Results
The prevalence of knee pain was 26.2 %, and that of low back pain was 29.3 %. Neighborhood walkability was positively associated with knee and low back pain after adjusting for individual confounders and mediators such as physical activity, a quarter increased perception of access to parks and sidewalks decreased the prevalence of knee pain (PR: 0.85, 95% CI: 0.77-0.94), a quarter increased perception of access to fresh food store decreased the prevalence of knee and low back pain (PR: 0.90, 95% CI: 0.84-0.96, PR: 0.92, 95% CI: 0.86-0.98), a quarter increased population density decreased the prevalence of knee and low back pain (PR: 0.95; 95% CI: 0.93-0.98, PR: 0.96; 95% CI: 0.94-0.98). This trend remains after adjusting the population density, and higher difficulty in walking due to slopes and stairs is newly significant to knee pain (PR: 1.09; 95% CI: 1.01-1.18).
Conclusions
Some of the neighborhood walkability has a protective relation to the knee and low back pain for older people. Longitudinal and intervention studies of the built environment for musculoskeletal pain are required.
Key messages
To our knowledge, this is the first study to discover that neighborhood walkability has a protective relation to knee and low back pain considering various adjustments in a large-scale survey. Improvement of built environments could potentially reduce musculoskeletal pain. In the future, not only individual factors but also environmental determinants of pain should be studied.

Abstract
Abstract
Introduction
Calcific aortic valve disease (CAVD) is one of the most common heart diseases worldwide, and its prevalence has increased in developed countries along with aging populations. Subclinical CAVD is characterized by aortic valve calcification (AVC) that may lead to aortic stenosis. AVC shares the same risk factors with atherosclerotic disease. Recently, nuclear magnetic resonance (NMR)-based lipoprotein particles, low-density and high-density lipoprotein particles (LDL-p, HDL-p) in particular, have emerged as novel markers of atherosclerotic disease. It has been unclear, however, whether NMR-based particles are associated with AVC.
Purpose
To examine cross-sectional association of NMR-based lipoprotein particles, standard lipids with AVC, and compare their strengths of association.
Methods
We studied a community-based random sample of Japanese men aged 40–79 years examined in 2006–08 in Japan. We excluded participants with history of myocardial infarction, stroke, aortic valve surgery, serum triglyceride concentration ≥400 mg/dl, estimated glomerular filtration rate (eGFR) <30 (ml/min/1.73m2), and use of lipid-lowering medication. We scored the degree of AVC according to Agatston's method, and defined prevalent AVC as the score >0. Lipoprotein particles were measured using NMR spectroscopy.
In our main analysis, we obtained multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) of prevalent AVC in the top quartile (Q4) for each lipid index in reference to the lowest quartile (Q1). Adjusting covariates include age, smoking, drinking, systolic blood pressure, glycated hemoglobin, medications for hypertension and/or for diabetes, eGFR, C-reactive protein. For sensitivity analysis, we repeated similar analyses presenting ORs per 1 standard deviation (SD) higher NMR-lipoproteins particles or standard lipids.
Results
Of 874 participants we analyzed, 153 (17.5%) men had AVC. The average (SD) age was 63.3 (10.0) years. Those with AVC tended to be older, likely to have clustering of atherosclerotic risk factors. Multivariable-adjusted ORs of prevalent AVC for Q4 versus Q1 were significantly positive for LDL-p [OR, 2.21 (95% CI: 1.24, 3.95] and low-density lipoprotein cholesterol (LDL-c) [2.17 (1.24, 3.80)]. In contrast, neither HDL-p nor high-density lipoprotein cholesterol (HDL-c) was significantly associated with AVC. In sensitivity analyses, however, the corresponding ORs per 1SD higher lipids/lipoprotein particles were smaller in LDL-p [1.33 (1.09, 1.63)] than LDL-c [1.41 (1.15, 1.73)]. The association of HDL-p became significant [1.28 (1.02, 1.61)] (per 1SD decrement) in the sensitivity analysis.
Conclusion
The overall associations of AVC with NMR-based lipoprotein particles (i.e. LDL-p, HDL-p) are comparable to those of standard lipids. This finding is parallel to the association between atherosclerotic cardiovascular diseases with NMR-based lipoproteins.

Abstract
Abstract
Background
Many studies have reported the J-shaped relationship between alcohol consumption and coronary heart disease (CHD) risk; therefore, light-drinkers is generally recognized to be associated with the lower risk of CHD. However, the mechanisms of lower risk for CHD in light-drinkers are still unclear. Alcohol drinking status is likely to be associated with not only CHD risk factors but also dietary intake. Nevertheless, few studies report these relationships in detail.
Purpose
The purpose of this study is to evaluate the relationships of alcohol drinking status with CHD classical risk factors and the intake of macro- and micro- nutrients in Japanese.
Methods
Study participants were 1,090 Japanese men and women aged 40–59 years from The INTERLIPID study excepted for 55 individuals who had missing data (n=26) and were past-drinkers (n=29). Alcohol consumption was assessed with two 7-day alcohol records, and average ethanol intake (per week) was calculated. Participants were classified into following 4 groups: non-drinkers (0g/week), light-drinkers (<100 g/week), moderate-drinkers (100–299 g/week), and heavy-drinkers (≥300 g/week). Serum LDL and HDL cholesterol, blood pressure (BP), the prevalence of hypertension and dyslipidemia, and smoking status were assessed as CHD risk factors. The intake of energy and macro- and micro-nutrients were evaluated from the four-timed in-depth 24-hr dietary recalls. Nutrient intake densities were calculated per total energy intake without alcohol. The analysis of variance and chi-squared test were used to evaluate the relations of alcohol status with CHD risk factors and nutrient intake.
Results
Serum HDL cholesterol levels increased and LDL cholesterol levels decreased with increasing alcohol consumption. Systolic and diastolic BP increased with increasing alcohol consumption. J-shaped relationships with alcohol consumption were observed for the proportion of current smoker, number of cigarettes, and the prevalence of hypertension; that is, light-drinkers was lowest among all groups. The prevalence of dyslipidemia was the highest in non-drinkers, and decreased with increasing alcohol consumption. In heavy-drinkers, total energy (kcal/day) was the highest, but energy intake without alcohol (kcal/day) was the lowest. For macronutrients, the intake of carbohydrate (%kcal) decreased, and the intakes of total and animal protein (%kcal) increased with increasing alcohol consumption. The intakes of total cholesterol (mg/1000kcal) and sodium (mg/1000kcal) increased, and total fiber (g/1000kcal) decreased with increasing alcohol consumption. These associations were similar in men and women.
Conclusions
Alcohol consumption was related with not only CHD classical risk factors but also the intake of macro- and micro-nutrients. Non-drinkers had a higher proportion of some CHD risk factors than light-drinkers. These results might influence on J-shaped relationship between alcohol consumption and CHD risk.

Abstract
As an alternative to Compton backscattering and bremsstrahlung, the process of colliding high-energy electron beams with strong laser fields can more efficiently provide both a cleaner and brighter source of photons in the multi-GeV range for fundamental studies in nuclear and quark-gluon physics. In order to favor the emission of high-energy quanta and minimize their decay into electron-positron pairs, the fields must not only be sufficiently strong, but also well localized. We here examine these aspects and develop the concept of a laser-particle collider tailored for high-energy photon generation. We show that the use of multiple colliding laser pulses with 0.4 PW of total power is capable of converting more than 18% of multi-GeV electrons passing through the high-field region into photons, each of which carries more than half of the electron initial energy.

Abstract
Natural disasters are often associated with forced residential relocation, thereby affected people experience a change of food environment that results in the increased body mass index. However, there are a few studies that examined whether a change in food environment caused risk of obesity after a natural disaster. To address this question, we leveraged a natural experiment of residential relocation in the aftermath of the 2011 Japan Earthquake and Tsunami. Our baseline data came from a nationwide cohort study of older community-dwelling adults conducted 7 months prior to the disaster. By chance, one of the field sites (Iwanuma City, Miyagi Prefecture) was directly in the line of the tsunami. Approximately 2.5 years after the disaster, we ascertained the residential addresses and health status of 3,594 survivors aged 65 years or older (82.1% follow-up rate). Fixed effects multinomial logistic regression showed that shortened distances to food outlets/bars increased the risks of transitioning from BMI in the normal range (18.5–22.9) to obesity (≥25.0) (Odds ratios: 1.46 for supermarkets; 1.43 for bars; 1.44 times for fast food outlets). Radically changed food access after a natural disaster may raise the risk of obesity among older survivors.
