Design and control of noise-induced synchronization patterns
We propose a method for controlling synchronization patterns of limit-cycle
oscillators by common noisy inputs, i.e., by utilizing noise-induced
synchronization. Various synchronization patterns, including fully synchronized
and clustered states, can be realized by using linear filters that generate
appropriate common noisy signals from given noise. The optimal linear filter
can be determined from the linear phase response property of the oscillators
and the power spectrum of the given noise. The validity of the proposed method
is confirmed by numerical simulations.Comment: 6 pages, 4 figure
Nematic transition and highly two-dimensional superconductivity in BaTiBiO revealed by Bi-nuclear magnetic resonance/nuclear quadrupole resonance measurements
In this Rapid Communication, a set of Bi-nuclear magnetic resonance
(NMR)/nuclear quadrupole resonance (NQR) measurements has been performed to
investigate the physical properties of superconducting (SC) BaTiBiO
from a microscopic point of view. The NMR and NQR spectra at 5~K can be
reproduced with a non-zero in-plane anisotropic parameter , indicating
the breaking of the in-plane four-fold symmetry at the Bi site without any
magnetic order, i.e., `the electronic nematic state'. In the SC state, the
nuclear spin-lattice relaxation rate divided by temperature, , does not
change even below , while a clear SC transition was observed with a
diamagnetic signal. This observation can be attributed to the strong
two-dimensionality in BaTiBiO. Comparing the NMR/NQR results among
BaTiO ( = As, Sb, and Bi), it was found that the normal and SC
properties of BaTiBiO were considerably different from those of
BaTiSbO and BaTiAsO, which might explain the two-dome structure
of in this system.Comment: 5 pages, 6 figure
Adalimumab Monotherapy in a Patient with Psoriatic Arthritis Associated with Chronic Renal Failure on Hemodialysis: A Case Report and Literature Review
We report a patient with psoriatic arthritis (PsA) who was successfully treated with adalimumab even while under hemodialysis therapy for associated chronic renal failure. Flow cytometry of circulating lymphocytes revealed an obvious decrease in both Th1 and Th17 cells after starting adalimumab. The latter returned to the pretreatment level in the course of adalimumab therapy, while the former did not. Adalimumab is a potent therapeutic option for PsA patients with chronic renal failure on hemodialysis, and Th1 in peripheral blood may reflect the disease activity
Deep Adversarial Reinforcement Learning With Noise Compensation by Autoencoder
We present a new adversarial learning method for deep reinforcement learning (DRL). Based on this method, robust internal representation in a deep Q-network (DQN) was introduced by applying adversarial noise to disturb the DQN policy; however, it was compensated for by the autoencoder network. In particular, we proposed the use of a new type of adversarial noise: it encourages the policy to choose the worst action leading to the worst outcome at each state. When the proposed method, called deep Q-W-network regularized with an autoencoder (DQWAE), was applied to seven different games in an Atari 2600, the results were convincing. DQWAE exhibited greater robustness against the random/adversarial noise added to the input and accelerated the learning process more than the baseline DQN. When applied to a realistic automatic driving simulation, the proposed DRL method was found to be effective at rendering the acquired policy robust against random/adversarial noise
Factors influencing vehicle passenger fatality have changed over 10 years: a nationwide hospital-based study.
Traffic injury trends have changed with safety developments. To establish effective preventive measures against traffic fatalities, the factors influencing fatalities must be understood. The present study evaluated data from a national medical database to determine the changes in these factors over time, as this has not been previously investigated. This observational study retrospectively analysed data from the Japanese Trauma Data Bank. Vehicle passengers involved in collisions from 2004-2008 and 2016-2017 were included. Data were compared between the two study periods, and between fatal and non-fatal patients within each period. Multivariate logistic regression analyses were performed to determine the factors influencing fatalities. In 2016-2017, patients were older and had lower fatality rates. In 2004-2008, fatalities were more likely to involve older male front-seat passengers with low d-BP, BT, and GCS values, and high AIS of the neck and abdomen. However, in 2016-2017, fatalities were more likely to involve older males with low GCS, high AIS of the abdomen, and positive focused assessment with sonography for trauma results. Our study identified independent factors influencing vehicle passenger fatalities, which will likely continue to evolve with the aging of the population and changing manners of injury.滋賀医科大学令和2年

A Case of Possible Concurrence of Dermatitis Herpetiformis and Linear Immunoglobulin A / Immunoglobulin G Bullous Dermatosis.
Linear immunoglobulin (Ig) A bullous dermatosis
(LABD), one subtype of subepidermal autoimmune
bullous skin diseases (AIBDs), is characterized by linear
deposit of only IgA along the basement membrane
zone (BMZ) on direct immunofluorescence (DIF) (1,2).
Patients showing linear deposits of both IgA and IgG
are diagnosed with linear IgA/IgG bullous dermatosis
(LAGBD) (3,4). Dermatitis herpetiformis (DH) is another
type of subepidermal AIBD characterized by clinically
pruritic erythematous skin lesions with vesicles on the
elbows, knees, and buttocks with granular IgA deposits
of IgA by DIF (5). In this study, we report a Japanese
case of a patient who showed possible concurrence of
DH and LAGBD based on clinical, histological, and immunological
findings
