AbstractThis paper introduces three catastrophic landslide disasters on the tectonic orogenic belt in Western Japan caused by rainfalls or earthquakes and the countermeasures against them. The first case story is the mega slide of Unzen-Mayuyama of Quaternary volcanic rock due to the 1792 earthquake. The landslide and subsequent tsunami caused the worst Japanese landslide-induced disaster in Shimabara and Ariake Bay. The stone pillars installed after the disaster, indicating the arrival points of the tsunami will generate awareness of the tsunami caused by landslides for future generations. Secondly, the Kumamoto earthquake of 2016 has induced many shallow landslides on tephra-covered slopes and massive slope failures that disrupted highway and rail traffic. Unmanned construction to secure workers has been introduced to stabilize the slope failure early. There is an urgent need for research on the identification of hazardous slopes for landslides on tephra-covered slopes. Thirdly, the Hiroshima disaster in 2018 was characterized by landslides, mainly in the suburban residential areas in Hiroshima City, where heavy rains have caused landslides from the weathered soil, so-called “Masa,” of granitic rocks. Similar disasters occurred in 1999 and 2014 in Hiroshima. The restoration project has been carried out by adopting necessary structural measures such as Sabo dams and non-structural measures such as land use regulations and/or early warning systems based on the Sediment Disaster Prevention Act.

Published: January 2023

AbstractThis paper describes the outline of the video tutorial prepared for vegetation workers and relevant officers in Bhutan to learn how vegetation works are to be done in remote areas. The Japan International Cooperation Agency (JICA for short) took a project on cutting unstable slopes in Gangthangkha, Wangdue, Bhutan, so that they should be gentler than 45° to improve slope stability with vegetation works. Particularly stabilizing slopes along Prime National Highway No. 1 (PNH-1 for short) was the overriding priority because slope failures along this highway have reportedly occurred in rainy seasons. Before vegetation works were carried out on the studied slope of the project, the authors conducted germination tests to choose seeds and methods suitable for the vegetation works. They chose Paspalum Atratum, Ruzi grass, and GM mixed (Grass Mixture seed formulating of Cock’s foot 70% and Italian Ryegrass 30% of 100 kg) based on their test results. The soil thickness associated with sowing was set at 5 cm. The authors tried the following types of vegetation methods on the studied site. Type A is arranging on the slope stripes of soil mixed with seeds and fertilizer, Type B is spreading out a five cm-thick seeds-mixed soil layer over the slope, and Type C is transplanting germination beds. In conclusion, Type C is the best in terms of its performance because the whole slope is quickly covered with already grown plants. In Type B, it is not until grass covers the entire slope that the slope is finally stabilized. Type A is good for seeds-mixed soil stripes, but it takes time for the grass to spread gradually over the whole slope.
Landslide Inventory Map of the Valemount Area, British Columbia, Canada. A Detailed Methodological Description
Authors: Bornaetxea Txomin , Blais-Stevens Andrée , Miller Brendan 
Published: January 2023

AbstractLandslides are a recurring geomorphological process in high mountainous areas like Valemount in the Canadian Rocky Mountains, British Columbia. The compilation of detailed information about the spatial distribution and characteristics of past landslides is essential for assessing future potential hazards. To provide baseline geoscience information to stakeholders and decision-makers, we carried out a landslide inventory that covers roughly 1200 km2. Using visual interpretation of aerial orthophotos, a digital elevation model of 5 × 5 m resolution and satellite imagery, we compiled up to 1286 landslides and classified them into 11 categories and three levels of certainty. The current paper describes the mapping methodology and summarizes our results.
Experimental Simulation of Landslide Creep in Ring Shear Machine
Authors: Bhandary Netra Prakash 
Published: January 2023

AbstractSoil material undergoes a volumetric change when deformed, and the change continues until the material reaches its critical state. In granular soils, the critical state is one that exhibits the least frictional resistance, but in clayey materials, the frictional resistance decreases further upon shearing due to particle reorientation in the plane of failure, and the material volume attains a stable or steady state only after a large amount of shear deformation, which depending on the material type varies from a few to tens of centimeters. This state of shear deformation is generally known as the residual state. This article focuses on residual-state creep shear tests on common clayey materials for the purpose of experimentally simulating the landslide creep and understanding the displacement behavior of large-scale creeping landslides. As a general understanding, the deep-seated creeping landslides displace as a result of residual-state shearing of clayey material in the slip surface. So, a modified bishop-type torsional ring shear machine was developed for studying the residual-state shear creep behavior of clayey soils. In the ring shear tests, the material is first sheared under a strain-controlled pattern, and after the sample reaches its residual state of shear, different sets of constant shear loads are applied until the sample fails again and again. The test results reveal that at the residual state of shear, the creep behavior is exhibited only after a load equivalent to the residual frictional resistance of the material is applied. Moreover, it was understood that the displacement required for the beginning of the tertiary stage of creep of particular soil material, i.e., the early stage of creep failure is the same for all sets of creep loads.
Integrable 3D lattice model in M-theory
Authors: Yagi Junya 
Published: January 2023

Abstract
It is argued that the supersymmetric index of a certain system of branes in M-theory is equal to the partition function of an integrable three-dimensional lattice model. The local Boltzmann weights of the lattice model satisfy a generalization of Zamolodchikov’s tetrahedron equation. In a special case the model is described by a solution of the tetrahedron equation discovered by Kapranov and Voevodsky and by Bazhanov and Sergeev.

Published: January 2023

Abstract
Purpose
To identify lesion characteristics associated with restenosis after endovascular therapy (EVT) for common femoral artery (CFA) lesions in patients with peripheral artery disease (PAD) in real-world practice.

Materials and Methods
We included 751 Japanese patients with PAD who underwent CFA EVT. Data were from a large-scale retrospective multicenter registry study. The association of lesion characteristics with the risk of restenosis was investigated with the Cox proportional hazards regression model.

Results
Lesions extended to the external iliac artery in 10.0% of patients, were isolated in the CFA in 59.9%, and involved the bifurcation in 30.1%. Chronic total occlusion was noted in 21.1%, and 99% stenosis, in 19.9%. Among the limbs with CFA lesions, 16.4% had a history of CFA EVT. Mean total lesion length was 32 ± 15 mm, and reference vessel diameter, 7.3 ± 1.4 mm. Plain old balloon angioplasty, drug-coated balloon angioplasty, and stent implantation were performed in 56.3, 23.2, and 20.5% of patients, respectively. The mean follow-up period was 10.4 ± 9.5 months. Rates of freedom from restenosis and reintervention at 1 year were 78.2 and 86.6%, respectively. Lesion characteristics independently associated with restenosis were history of CFA EVT, reference vessel diameter less than 6 mm, and lesion length greater than or equal to 50 mm; adjusted hazard ratios were 1.63 (P = 0.007), 1.93 (P = 0.006), and 1.71 (P = 0.018), respectively.

Conclusion
History of CFA EVT, smaller reference vessel diameter, and longer lesion length are independent risk factors for restenosis after CFA EVT.

Breakdown of Heteroclinic Connections in the Analytic Hopf-Zero Singularity: Rigorous Computation of the Stokes Constant
Authors: Baldomá Inmaculada , Capiński Maciej J. , Guardia Marcel , Seara Tere M. 
Published: January 2023

AbstractConsider analytic generic unfoldings of the three- dimensional conservative Hopf-zero singularity. Under open conditions on the parameters determining the singularity, the unfolding possesses two saddle-foci when the unfolding parameter is small enough. One of them has one-dimensional stable manifold and two-dimensional unstable manifold, whereas the other one has one- dimensional unstable manifold and two-dimensional stable manifold. Baldomá et al. (J Dyn Differ Equ 25(2):335–392, 2013) gave an asymptotic formula for the distance between the one-dimensional invariant manifolds in a suitable transverse section. This distance is exponentially small with respect to the perturbative parameter, and it depends on what is usually called a Stokes constant. The nonvanishing of this constant implies that the distance between the invariant manifolds at the section is not zero. However, up to now there do not exist analytic techniques to check that condition. In this paper we provide a method for obtaining accurate rigorous computer-assisted bounds for the Stokes constant. We apply it to two concrete unfoldings of the Hopf-zero singularity, obtaining a computer-assisted proof that the constant is nonzero.

Abstract
Background
Retinal degeneration leading to optical coherence tomography (OCT) changes is frequent in patients with multiple sclerosis (PwMS).

Objective
To investigate associations among OCT changes, MRI measurements of global and regional brain volume loss, and physical and cognitive impairment in PwMS.

Methods
95 PwMS and 52 healthy controls underwent OCT and MRI examinations. Mean peripapillary retinal nerve fiber layer (pRNFL) thickness and ganglion cell/inner plexiform layer (GCIPL) volume were measured. In PwMS disability was quantified with the Expanded Disability Status Scale (EDSS) and Symbol Digit Modalities Test (SDMT). Associations between OCT, MRI, and clinical measures were investigated with multivariable regression models.

Results
In PwMS, pRNFL and GCIPL were associated with the volume of whole brain (p < 0.04), total gray matter (p < 0.002), thalamus (p ≤ 0.04), and cerebral cortex (p ≤ 0.003) –both globally and regionally–, but not white matter. pRNFL and GCIPL were also inversely associated with T2-lesion volume (T2LV), especially in the optic radiations (p < 0.0001). The brain volumes associated with EDSS and SDMT significantly overlapped with those correlating with pRNFL and GCIPL.

Conclusions
In PwMS, pRNFL and GCIPL reflect the integrity of clinically-relevant gray matter structures, underling the value of OCT measures as markers of neurodegeneration and disability in multiple sclerosis.

Published: January 2023

Abstract
Background
Evaluation of the application of CSF real-time quaking-induced conversion in Creutzfeldt–Jakob disease surveillance to investigate test accuracy, influencing factors, and associations with disease incidence.

Methods
In a prospective surveillance study, CSF real-time quaking-induced conversion was performed in patients with clinical suspicion of prion disease (2014–2022). Clinically or histochemically characterized patients with sporadic Creutzfeldt–Jakob disease (n = 888) and patients with final diagnosis of non-prion disease (n = 371) were included for accuracy and association studies.

Results
The overall test sensitivity for sporadic Creutzfeldt–Jakob disease was 90% and the specificity 99%. Lower sensitivity was associated with early disease stage (p = 0.029) and longer survival (p < 0.001). The frequency of false positives was significantly higher in patients with inflammatory CNS diseases (3.7%) than in other diagnoses (0.4%, p = 0.027). The incidence increased from 1.7 per million person-years (2006–2017) to 2.0 after the test was added to diagnostic the criteria (2018–2021).

Conclusion
We validated high diagnostic accuracy of CSF real-time quaking-induced conversion but identified inflammatory brain disease as a potential source of (rare) false-positive results, indicating thorough consideration of this condition in the differential diagnosis of Creutzfeldt–Jakob disease. The surveillance improved after amendment of the diagnostic criteria, whereas the incidence showed no suggestive alterations during the COVID-19 pandemic.
Automated macular segmentation can distinguish glaucomatous from compressive optic neuropathy
Authors: Soares Ricardo Machado , Braga Joana Figueiredo , da Silva Fernandes Joana , Ferreira Catarina Cunha , Ribeiro Lígia , Alves Hélio , Meira Dália 
Published: January 2023

Abstract
Purpose
To compare macular damage in glaucomatous optic neuropathy (GON) and compressive optic neuropathy (CON) and assess its diagnostic accuracy in distinguishing between diseases.

Methods
Observational, cross-sectional, single-center study. Patients with GON, CON, and healthy controls were included according to the eligibility criteria. An automated spectral-domain optical coherence tomography (SD-OCT) algorithm was used to segment the circumpapilary retinal nerve fiber layer (cpRNFL) and macula. The layer thickness was measured in each sector according to the Early Treatment Diabetic Retinopathy Study and the 6-sector Garway-Heath-based grids. Data was compared across all study groups, and the significance level was set at 0.05.

Results
Seventy-five eyes of 75 participants, 25 with GON, 25 with CON, and 25 healthy controls (CG), were included. Macular thickness was diminished in the ganglion cell complex of GON and CON patients compared to CG (p<0.05). The best Garway-Heath-based grid parameters for distinguishing GON and CON were the nasal-inferior (NI) and nasal-superior sectors and the NI/temporal inferior (TI) damage ratios in the macular ganglion cell (mGCL) and inner plexiform (IPL) layers. Moreover, the combination of the NI sector and NI/TI damage ratios in both layers had higher discriminative power (AUC 0.909; 95% CI 0.830–0.988; p<0.001) than combining parameters in each layer separately.

Conclusion
Our findings suggest that the evaluation of macular segmented layers damage by SD-OCT may be a helpful add-on tool in the differential diagnosis between GON and CON.
The challenge of optimizing supports for people living with and beyond cancer: creating proximity between cancer and non-profit community-based providers
Authors: Tremblay Dominique , Touati Nassera , Usher Susan , Gentil Barbara , Courval Marie-Josée 
Published: January 2023

Abstract
Purpose
Non-profit community-based organizations (CO) remain insufficiently integrated into cancer networks. Drawing on dimensions of proximity, this study explores how and why coordination between cancer teams and COs is established and solidified.

Methods
A descriptive interpretive study is undertaken in Québec (Canada), where a cancer program has long promoted the integration of COs in the cancer trajectory. Semi-directed interviews with providers, managers and people living with and beyond cancer (total n = 46) explore the challenges of coordination between cancer and CO providers, along with facilitating or impeding factors. Three main themes related to coordination in cancer networks emerge, which are analyzed by operationalizing the multi-dimensional framework of proximity.

Results
Findings reveal a lack of cognitive proximity, which calls for efforts to both identify patient needs and increase cancer team knowledge and appreciation of CO resources. Organizational proximity refers to systems and rules that facilitate interactions, and we find that referral mechanisms and communication channels are inadequate, with patients often playing a linking role despite barriers. Coordination improves when relational proximity is established between cancer and CO teams, and this can be enhanced by geographic proximity; in one region, COs have a physical presence within the cancer center.

Conclusion
Integrating COs into the cancer network can help meet the spectrum of needs faced by people living with and beyond cancer. This study offers managers and decision-makers insight into how coordination between cancer teams and COs can be supported. Proximity allows the distinct contributions of actors to be considered in context and contributes to understanding the “how” of integrated practice.
Adverse events in neurosurgery: a comprehensive single-center analysis of a prospectively compiled database
Authors: Dao Trong Philip , Olivares Arturo , El Damaty Ahmed , Unterberg Andreas 
Published: January 2023

Abstract
Purpose

To prospectively identify and quantify neurosurgical adverse events (AEs) in a tertiary care hospital.

Methods
From January 2021 to December 2021, all patients treated in our department received a peer-reviewed AE-evaluation form at discharge. An AE was defined as any event after surgery that resulted in an undesirable clinical outcome, which is not caused by the underlying disease, that prolonged patient stay, resulted in readmission, caused a new neurological deficit, required revision surgery or life-saving intervention, or contributed to death. We considered AEs occurring within 30 days after discharge. AEs were categorized in wound event, cerebrospinal fluid (CSF) event, CSF shunt malfunction, post-operative infection, malpositioning of implanted material, new neurological deficit, rebleeding, and surgical goal not achieved and non-neurosurgical AEs.

Results
2874 patients were included. Most procedures were cranial (45.1%), followed by spinal (33.9%), subdural (7.7%), CSF (7.0%), neuromodulation (4.0%), and other (2.3%). In total, there were 621 AEs shared by 532 patients (18.5%). 80 (2.8%) patients had multiple AEs. Most AEs were non-neurosurgical (222; 8.1%). There were 172 (6%) revision surgeries. Patients receiving cranial interventions had the most AEs (19.1%) although revision surgery was only necessary in 3.1% of patients. Subdural interventions had the highest revision rate (12.6%). The majority of fatalities was admitted as an emergency (81/91 patients, 89%). Ten elective patients had lethal complications, six of them related to surgery (0.2%).

Conclusion
This study presents the one-year results of a prospectively compiled AE database. Neurosurgical AEs arose in one in five patients. Although the need for revision surgery was low, the rate of AEs highlights the importance of a systematic AE database to deliver continued high-quality in a high-volume center.
