Authors: Tang Huiming , Wang Liangqing , Li Changdong , Zou Zongxing 
Published: January 2023

AbstractThe essence of reservoir landslide treatment is to change its evolution process. It is hard to guarantee the effectiveness and safety of the landslide prevention and control technology that ignores the evolution processes. Guided by the thought of evolution, this study introduced some key techniques of reservoir landslide prevention and control. Seven evolution modes are summarized for rock slides and the optimal control measures suitable for each evolution mode and different evolution stages are suggested. The dynamic stability evaluation method is proposed considering the evolution process of the slip zone soil strength. This study introduces the methods for determining optimal pile positions for step-shaped sliding surfaces, the optimal plane arrangement of stabilizing piles, and their reasonable embedded lengths. Finally, two demonstration bases for comprehensive prevention and control of large reservoir landslides that were established in the Three Gorges Reservoir area (TGRA) were introduced, which is of great scientific and application value to the improvement of reservoir landslide prevention and control techniques.

Published: January 2023

AbstractLandslide disasters in Bangladesh’s Chittagong hill districts (CHD) put lives, livelihood, and the ecosystem at risk. Therefore, understanding the causes of landslide events in CHD is crucial to preparing and implementing disaster risk reduction (DRR) strategies. The causes of landslides are generally seen through the lenses of physical science. However, to better understand the landslide disaster mechanism, it is essential to explore the human activities that trigger and aggravate the events. This article uses qualitative social science tools and techniques to investigate CHD’s anthropogenic-induced landslide disasters. Forty key informants from diverse professions, ethnicities, communities, and backgrounds were interviewed between 9 June and 3 November 2020. The recorded interviews were translated, transcribed, and thematically analysed in NVivo software. The results show that human-induced landslides in CHD evolve around three broader areas: demography, climate change, and lack of coordination and regulation. First, increased population, hill cutting, deforestation, manipulated agricultural practices, and sand and stone extraction is the leading anthropogenic activities of landslides in CHD. Second, the influx of Rohingya refugees into Bangladesh significantly increased landslide vulnerability. Third, climate change-induced erratic rainfall is leading to more rainfall-induced landslides. Finally, a lack of coordination and regulations among various institutions hinders the DRR process. The short, medium- and long-term recommendations include stopping illegal hill cutting and deforestation, regulating heavy vehicles, increasing coordination, institutionalising early warning systems, conducting massive awareness campaigns, conducting further research, addressing challenges such as lightning, climate migration and conflict, and creating a master plan exclusive for the entire region and coming up with a political consensus for better implementation of the plan.
Suffosion Landslides as a Specific Type of Slope Deformations in the European Part of Russia
Authors: Zerkal Oleg V. , Barykina Olga S. 
Published: January 2023

AbstractLandslide classification systems are based on the analysis of mechanisms of slope deformation and consideration of landslide-forming earth materials. The main types of landslide movement are fall, topple, slide, spread and flow. Within the European part of Russia, a specific type of slope deformation is often observed, where suffosion (the process of washout and mechanical removal of fine particles from saturated soils under the influence of infiltrating groundwater flow) plays an essential role. Suffosion landslides are defined as a type of complex landslide formed in regions characterized by alternating horizons of unsaturated and saturated sands, loams and clays. Such hydrogeological conditions occur in the European part of Russia, most of which is occupied by the East European Plain. In the East European Plain, suffosion landslides are confined to the valleys of large rivers and their tributaries (Volga, Oka, Don, etc.), where their volumes can reach several million m3. In the Volgograd and Moscow regions, suffosion can result in soil decompaction at the base of slopes, or the formation of underground cavities in massifs, niches and grottoes on slopes, ultimately leading to the formation of suffosion landslides. Suffosion landslides are complex displacements of waterlogged soil masses formed as a result of suffosion and the subsequent associated collapse of the sides of suffosion cavities and niches. Indicators of suffosion landslides are: (1) the presence of a prograding fan of finely dispersed material at the base of slope and adjacent terrain, whose boundaries often exceed the landslide limits; and (2) a large number of ledges of different sizes on the surface of the landslide body created by uneven settling of blocks into the roof of suffosion cavities, and on the sides of suffosion niches. Suffosion landslides are often elongated, horseshoe-shaped, or ∞-shaped with a narrowing in the central part formed in saturated soils breaching from an underground suffosion cavity. Suffosion landslides do not have a marked sliding surface. Rather, soil displacement occurs over layers with strongly dispersed groundwater. The displacement rate of such landslides depends on the scale and speed of development of mechanical suffosion at the base of the slope.

Published: January 2023

AbstractAlthough GPUs have been used to accelerate various convolutional neural network algorithms with good performance, the demand for performance improvement is still continuously increasing. CPU/GPU overclocking technology brings opportunities for further performance improvement in CPU-GPU heterogeneous platforms. However, CPU/GPU overclocking inevitably increases the power of the CPU/GPU, which is not conducive to energy conservation, energy efficiency optimization, or even system stability. How to effectively constrain the total energy to remain roughly unchanged during the CPU/GPU overclocking is a key issue in designing adaptive overclocking algorithms. There are two key factors during solving this key issue. Firstly, the dynamic power upper bound must be set to reflect the real-time behavior characteristics of the program so that algorithm can better meet the total energy unchanging constraints; secondly, instead of independently overclocking at both CPU and GPU sides, coordinately overclocking on CPU-GPU must be considered to adapt to real-time load balance for higher performance improvement and better energy constraints. This paper proposes an Adaptive Overclocking Algorithm (AOA) on CPU-GPU heterogeneous platforms to achieve the goal of performance improvement while the total energy remains roughly unchanged. AOA uses the function $$F_k$$

AbstractCross-platform power/performance prediction is becoming increasingly important due to the rapid development and variety of software and hardware architectures in an era of heterogeneous multi-core.

A comment on loop corrections to the celestial stress tensor
Authors: Pasterski Sabrina 
Published: January 2023

Abstract
In this note we show how the 1-loop exact correction to the subleading soft graviton theorem arising from IR divergences of scattering amplitudes matches onto the quadratic corrections to the soft charges computed from the BMS flux algebra. In the process, we examine how the BMS flux construction extends the celestial diamond framework to non-linear order and non-trivial vacua, and provides the natural symmetry generators for Celestial CFT.
Universal accelerating cosmologies from 10d supergravity
Authors: Marconnet Paul , Tsimpis Dimitrios 
Published: January 2023

Abstract
We study 4d Friedmann-Lemaître-Robertson-Walker cosmologies obtained from time-dependent compactifications of Type IIA 10d supergravity on various classes of 6d manifolds (Calabi-Yau, Einstein, Einstein-Kähler). The cosmologies we present are universal in that they do not depend on the detailed features of the compactification manifold, but only on the properties which are common to all the manifolds belonging to that class. Once the equations of motion are rewritten as an appropriate dynamical system, the existence of solutions featuring a phase of accelerated expansion is made manifest. The fixed points of this dynamical system, as well as the trajectories on the boundary of the phase space, correspond to analytic solutions which we determine explicitly. Furthermore, some of the resulting cosmologies exhibit eternal or semi-eternal acceleration, whereas others allow for a parametric control on the number of e-foldings. At future infinity, one can achieve both large volume and weak string coupling. Moreover, we find several smooth accelerating cosmologies without Big Bang singularities: the universe is contracting in the cosmological past (T < 0), expanding in the future (T > 0), while in the vicinity of T = 0 it becomes de Sitter in hyperbolic slicing. We also obtain several cosmologies featuring an infinite number of cycles of alternating periods of accelerated and decelerated expansions.

Optimal vaccination: various (counter) intuitive examples
Authors: Delmas Jean-François , Dronnier Dylan , Zitt Pierre-André 
Published: January 2023

AbstractIn previous articles, we formalized the problem of optimal allocation strategies for a (perfect) vaccine in an infinite-dimensional metapopulation model. The aim of the current paper is to illustrate this theoretical framework with multiple examples where one can derive the analytic expression of the optimal strategies. We discuss in particular the following points: whether or not it is possible to vaccinate optimally when the vaccine doses are given one at a time (greedy vaccination strategies); the effect of assortativity (that is, the tendency to have more contacts with similar individuals) on the shape of optimal vaccination strategies; the particular case where everybody has the same number of neighbors.

Abstract
Aim
This European multicentric study aimed to prove safety and performance of the Bonebridge BCI 602 in children and adults suffering from either conductive hearing loss (CHL), mixed hearing loss (MHL), or single-sided sensorineural deafness (SSD).

Methods
33 patients (13 adults and 10 children with either CHL or MHL and 10 patients with SSD) in three study groups were included. Patients were their own controls (single-subject repeated measures), comparing the unaided or pre-operative to the 3-month post-operative outcomes. Performance was evaluated by sound field thresholds (SF), word recognition scores (WRS) and/or speech reception thresholds in quiet (SRT) and in noise (SNR). Safety was demonstrated with a device-specific surgical questionnaire, adverse event reporting and stable pure-tone measurements.

Results
The Bonebridge BCI 602 significantly improved SF thresholds (+ 25.5 dB CHL/MHL/SSD), speech intelligibility in WRS (+ 68.0% CHL/MHL) and SRT in quiet (− 16.5 dB C/MHL) and in noise (− 3.51 dB SNR SSD). Air conduction (AC) and bone conduction (BC) thresholds remained stable over time. All adverse events were resolved, with none unanticipated. Mean audio processor wearing times in hours [h] per day for the CHL/MHL group were ~ 13 h for adults, ~ 11 h for paediatrics and ~ 6 h for the SSD group. The average surgical length was 57 min for the CHL/MHL group and 42 min for the SSD group. The versatility of the BCI 602 (reduced drilling depth and ability to bend the transition for optimal placement) allows for treatment of normal, pre-operated and malformed anatomies. All audiological endpoints were reached.

Conclusions
The Bonebridge BCI 602 significantly improved hearing thresholds and speech understanding. Since implant placement follows the patient’s anatomy instead of the shape of the device and the duration of surgery is shorter than with its predecessor, implantation is easier with the BCI 602. Performance and safety were proven for adults and children as well as for the CHL/MHL and SSD indications 3 months post-operatively.
Ocean model with adjustable arrangements of discrete variables: application to strong tidal flows and low-salinity water dynamics

Published: January 2023

AbstractThe assessment of marine environmental risk necessitates the simulation of a series of phenomena related to the risk as well as a measurement of creatures exposed to the risk. As a practical tool, the simulation is based on the establishment of a numerical ocean model. Although several decades have passed since the numerical model for ocean dynamics has been presented, there remains room for fundamental approaches to refine the method for computing solutions. This paper is a report of the development of a novel algorithm of the model. In this algorithm, discrete variables are positioned in a grid to maximally elicit the advantages of a numerical scheme adopted to each term in the governing equations and simplify the program structure. The implemented program is applied to a tidal flow and riverine buoyant plume in the Hinchinbrook Channel in the eastern coast of the Australian Continent. The computation reproduces the observed strong oscillatory flows and low-salinity water dynamics well. The proposed method is applicable to the movements of pollutants in regions of freshwater influence.

Published: January 2023

AbstractCase hardening represents the most important heat treatment process to increase the load carrying capacity of gear components. Beside predominantly martensitic surface layers with low proportion of retained austenite, there were investigated material structures with differing properties in preceding research work.In a previous publication, the results of three variants made of the material 20MnCr5, which is typically used for gears, were presented. The reference heat treatment was a conventional carburizing with subsequent case hardening. The second variant was also gas carburized, but with a high proportion of retained austenite. The last presented variant had a bainitic structure in the surface layer. The second and the third variant showed a similar tooth root bending strength compared to the reference. The numbers of the pitting resistance were significantly higher than for the reference variant.This paper presents the results of further investigations on the influence of different microstructures on the gear load carrying capacity. For this purpose, gears made of 18CrNiMo7‑6 were tested with regard to their load carrying capacity. 18CrNiMo7‑6 is a case hardening steel like 20MnCr5, too, which is often applied in big gear components. The tooth root bending strength was approximately constant, whereas the pitting resistance decreased compared to the corresponding variants of the material 20MnCr5. In comparison to the carburized 20MnCr5 reference variant, only the 18CrNiMo7‑6 variant with a large proportion of retained austenite showed a higher pitting resistance.The tooth root bending strength investigations took place in the cycle regime of limited life as well in the high cycle fatigue regime. The pitting resistance was only determined in the cycle regime of limited life.

AbstractNext-generation sequencing-based microbiological analysis is a complex way to profile vaginal microbiome samples since each step affects the results gained. Methodologies for sample collection lack golden standards. We compared Puritan DNA/RNA swab (PS) and Copan FLOQ swab (CS) and provided consistent and reliable microbiome profiles analyzed by 16S rRNA gene sequencing. We collected two consecutive vaginal samples utilizing PS with room temperature storing and CS with instant freezing from 26 women. Variable region 4 of bacterial 16S rRNA gene was amplified with single PCR by custom-designed dual-indexed primers and sequenced with Illumina MiSeq system. Read quality control, operational taxonomic unit tables, and alpha and beta diversities analysis were performed, and community richness, diversity, and evenness were evaluated and compared between the two samplings and tests. Nineteen sample pairs produced detectable, intact DNA during the extraction protocol and/or further microbial profiles. Alpha bacterial diversity indices were independent on the collection protocol. No significant statistical differences were found in the measured beta diversity metrics between the collection methods. Of the women, 43% had Lactobacillus-dominated vaginal microbiome profile despite of collection method. Previously reported important vaginal microbiome phyla Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, and Proteobacteria were present in the sample set although their relative abundances varied among individuals. PS and CS enable constant vaginal microbiota sampling. The PS method with no need for instant freezing is suitable for on-site collections at clinics. Furthermore, it seems to be possible to take two samples instead of one with constant microbiological results.
Corporate income tax competition and efficient tax base equalization
Authors: Matsumoto Mutsumi , Ogawa Hikaru 
Published: January 2023

AbstractThe literature on tax competition argues that the representative tax system (RTS), which is a standard form of tax base equalization, can internalize interregional externalities due to capital mobility. Although this conventional view holds when per unit tax on capital is imposed, it does not hold when corporate income is subject to tax. This paper proposes an efficient tax base equalization system under which each region’s tax base is evaluated by the average factor return of all regions, not by each region’s factor return (as in RTS). By investigating the nature of externalities arising from non-cooperative tax policy, we explain the workings of our “average-return” tax base equalization system.
Fish yawn: the state-change hypothesis in juvenile white-spotted char Salvelinus leucomaenis
Authors: Yamada Hiroyuki , Wada Satoshi 
Published: January 2023

AbstractYawning is a ubiquitous stereotyped action in vertebrates. Yawning may induce behavioral state changes in animals through its arousal function, but no studies have explicitly examined this state-change hypothesis in fish. This study examined the state-change hypothesis in juvenile white-spotted char, Salvelinus leucomaenis. We observed 48 yawns in 23 out of 41 juveniles during 600 s of observation in the laboratory. Thirty-two of these yawns occurred while juveniles were stationary on the substrate, and they were concentrated immediately before the behavioral transition from stationary to active. These results support the state-change hypothesis. Sixteen yawns were observed after the behavioral transition, and their durations were longer than those before the transition. Although we suspected that this prolonged yawning after the transition would be associated with feeding and thermoregulation in the juveniles, we could not determine the cause of this difference. Further studies are needed to understand fish yawning and the origin of animal yawning.
