PanoNetVLAD: Visual Loop Closure Detection in Continuous Space Represented with Panoramic View Using Multiple Cameras

This study deals with the problem of visual loop closure detection that occurs when there are limited camera field of views. The proposed method generates a panoramic image using multiple images and creates sub-panorama images through the sliding window process. Then, a learning-based descriptor is formed for robust feature detection even in illumination changes and challenging environments. After that, the index of the sub-panorama image descriptor, which is closest to the query image descriptor, is found, and the final candidate is found which has the same index with the image of the raw database. Histogram equalization and image masking were conducted to create a robust panorama image before examining our proposed method. To prove the effectiveness of our proposed algorithm, a dataset trajectory was acquired in which visual loop detection was difficult. In addition, datasets were obtained indoors and outdoors to check whether the proposed algorithm is applicable to various environments. The acquired dataset is shared through the GitHub page at https://github.com/SungJaeShin/KAIST-DP.
Mais et associés

This paper focuses on the distribution of discourse marker sequences immediately on the left or right of mais (≈ but) in French, such as oui non mais (≈ yes no but), mais quand même (≈ but still) or mais bon (≈ but well). The goal is to determine what sequences are the most frequent and how they fit (or not) with the meaning of mais. Exploiting five spoken French corpora, we use two association measures to extract the most plausible candidate patterns. Following the literature on association measures, we explore the two complementary dimensions of frequency (MI3 measure) and predictability (DeltaP measure). This procedure reveals that i) there are indeed discourse marker patterns around bon, ii) most clusters or associates smoothly combine with the basic ‘argumentative’ value of mais and iii) within this semantically coherent set, comparing and crossing the results of the two measures on the left and the right of mais helps to identify subsets of discourse markers with specific discourse functions.
The effects of scale, space and time on the predictive accuracy of land use models

The econometric literature about modeling land use choices is highly heterogeneous with respect to the scale of the data, and to the structure of the models in terms of the effects of space and time. This paper proposes a joint evaluation of each of these three elements by estimating a broad spectrum of individual and aggregate, spatial and aspatial, short and long run econometric models on the same detailed French dataset. Considering four land use classes (arable crops, pasture, forest, and urban), all the models are compared in terms of both in- and out-of-sample predictive accuracy. We argue that the aggregate scale allows to model more effectively the effect of space by using spatial econometric models. We show that modeling spatial autocorrelation allow to have very accurate predictions which can even outperform individual models when the appropriate predictors are used. We also found some strong interactions between the effects of scale, space and time which can be of major interest for applied researchers.
Determining Hot Deformation Behavior and Rheology Laws of Selected Austenitic Stainless Steels

Due to their versatile properties, austenitic stainless steels have a wide application potential, including in specific fields, such as the nuclear power industry. ChN35VT steel is a chromium–nickel–tungsten type of steel stabilized by titanium, and it is suitable for parts subjected to considerable mechanical stress at elevated temperatures. However, the available data on its deformation behavior at elevated/high temperatures is scarce. The core of the presented research was thus the experimental characterization of the deformation behavior of the ChN35VT steel under hot conditions via the determination of flow stress curves, and their correlation with microstructure development. The obtained data was further compared with data acquired for 08Ch18N10T steel, which is also known for its applicability in the nuclear power industry. The experimental results were subsequently used to determine the Hensel-Spittel rheology laws for both the steels. The ChN35VT steel exhibited notably higher flow stress values in comparison with the 08Ch18N10T steel. This difference was more significant the lower the temperature and the higher the strain rate. Considering the peak stress values, the lowest difference was ~8 MPa (1250 °C and 0.01 s−1), and the highest was ~150 MPa (850 °C and 10 s−1). These findings also corresponded to the microstructure developments—the higher the deformation temperature, the more negligible the observed differences as regards the grain size and morphology.
A PILOT STUDY ON DIABETIC PATIENTS AT MALANG COMMUNITY HEALTH CENTER REGARDING THE APPLICATION OF THE T-PLATE MODEL CONCEPT

Introduction: Diabetes mellitus is a comorbidity that is often found in Covid-19 patients with a 3.9-fold risk of death. Data from the Malang City Health Office shows an increase in the number of diabetes patients by 1.2% each year. In Indonesia, 3J (right amount, type, and eating time) has become the principle of diabetes diet therapy, but in practice, it is still challenging to apply independently. Aims: Investigating the T-Plate Model as a simple eating guide for people with diabetes mellitus. Methods: This pilot study included 18 diabetic patients at some Primary Health Care who were 50–70 years old and had a BMI more than 23 kg/m2. The participant was split into two groups, with nine people in the (C) group eating according to the T-Plate Model, and others in the (T) group eating according to the T-Plate Model after eating fruit. After a 3-month treatment period, BMI, blood pressure, carbohydrate, and fiber consumption were assessed. Mean BMI and blood pressure were examined using paired sample t-tests (p 0.05). Results: Both groups' BMIs fell into the category of obesity level 1 before to treatment periods: C group (26.09+3.13 kg/m2) and T group (27.15+ 4.15). We discovered significant blood pressure and BMI variations in the T group at the end of intervention periods (p 0.05). Nevertheless, systolic blood pressure was different in the C group (p 0.05). Conclusions: It may be inferred that using the T-Plate Model with the addition of fruit initially can lower blood pressure and BMI.
JeuxDeMots : Un réseau lexico-sémantique pour le français, issu de jeux et d’inférences

The JeuxDeMots project aims to build a broad knowledge base in French, both common sense and specialised, using games, contributory approaches, and inference mechanisms. A dozen games have been designed as part of this project, each one allowing collecting specific information, or to consolidate the information acquired through the other games. This article describes, both qualitatively and quantitatively, the data collected and constructed since the launch of the project in the summer of 2007. In particular, we discuss the following aspects: the structure of the lexical and semantic network, some types of relations (semantic, ontological, subjective, semantic roles, associations of ideas), annotation of relations (meta-information), semantic refinements (management of polysemy), the creation of clusters allowing the representation of richer knowledge (n-argument relations). Finally, we will describe some complementary acquisition methods such as a bot for endogenous contributions as well as a chatbot making inferences.
Global Research Hotspots in Venous Thromboembolism Anticoagulation: A Knowledge-Map Analysis from 2012 to 2021

Background Venous thromboembolism (VTE) is a common cardiovascular disease that seriously threatens human lives. Anticoagulant therapy is considered to be the cornerstone of VTE treatment. An increasing number of studies has been updated in the VTE anticoagulation field. However, no bibliometric analyses have assessed these publications comprehensively. Therefore, our study aimed to analyze the global status, hotspots, and trends of anticoagulant therapy for VTE. Methods The relevant literature on VTE anticoagulation published between 2012 and 2021 was retrieved and collected from the Web of Science Core Collection database. VOSviewer, Cooccurrence Matrix Builder, gCLUTO, and some online visualization tools were adopted for bibliometric analysis. Results A total of 15,152 related articles were retrieved. In recent years, the research output of VTE anticoagulation gradually increased. The United States was the most productive country. International cooperation is concentrated in North America and Europe; the most influential documents, journals, authors, and organizations were also from these two continents. Research hotspots mainly focus on clinical guidelines, VTE in special populations, non-vitamin K oral anticoagulants (NOACs), and parenteral anticoagulation. The research frontiers and trends include the assessment of NOACs and the antithrombotic management of VTE complicated with coronavirus disease 2019 (COVID-19). Conclusion This bibliometric analysis provides a systematic overview of the VTE anticoagulation research, which will facilitate researchers to better understand the situation of VTE anticoagulation. Future studies should be dedicated to NOACs application and VTE-combined COVID-19 patients.
Barriers to Lifestyle Modification Compliance among Type 2 Diabetic Patients in Lesotho

Diabetes mellitus (DM) has been considered a serious long-term condition which is one of the top 10 causes of death among adults and it has got a major impact on lives and well-being of individuals, families and societies. The most common type of DM in Africa is Type2 (T2DM). Diabetes being a major problem worldwide, healthy eating coupled with regular physical activity help in achieving a good glycemic control as well as delaying and reducing the onset of commonest diabetes complications. The current study aimed at exploring the barrier to lifestyle modification compliance among type 2 diabetic clients at Paki health center Lesotho. In this study, a quantitative descriptive design was applied in exploring the barriers of compliance to lifestyle modifications (diabetes self- management) among adults with type 2 diabetes. Data was collected using semi-structured questionnaires, which were administered to 40 study participants who were purposively selected for inclusion into study. The study revealed that among other factors, financial constraints 21participants (52.5%) is associated with non- compliance to healthy eating habits. Other reasons from non-compliance to healthy eating were identified as absence of written instructions, sickness, lack of stamina to exercise, laziness and lack of access to physical activity facilities with percentages 85%, 65%, 50% and 40% respectively. Thus, study findings reveal needs for continuous health education on health benefits of healthy eating habits and physical activity.

Old Halfeti, the subject of the study, stands in 130 km west of Şanliurfa city center, in the east of Firat River and on 388 m height. While old Halfeti was a town related to city of Şanliurfa, after the year 2000, 2/5 (180 hectar) of old Halfeti was covered with the water of dam lake as a result of completion of Birecik Dam that is a part of GAP. Whole of the region except two districts have been moved to the region of Karaotaklak since 1999 by the completion of Birecik dam. Rustiye and Şimaliye regions that remained in old Halfeti have been united to New Halfeti. Halfeti, with its natural beauty, boat excursions on Birecik Dam Lake, its architecture and Siyahgul, became the member of Cittaslow (peaceful city) in 2013 and takes attention as its historical structures stays under the lake. Furthermore, it has been a region visited frequently by tourists in recent years because of its location being near to some touristic places such as Rumkale, Zeugma, Savasan Koyu, Erenkoy. In this study, old Halfeti (Şanliurfa) that has developed with its peripheral in terms of tourism sector will be analyzed.
Etude des causes de prolifération de microalgues toxiques en mer: Cas d'Alexandrium

Differentes especes phytoplanctoniques ont ete a l'origine d'efflorescences toxiques sur l'ensemble du littoral francais ces dernieres annees. Parmi celles-ci, les efflorescences de l'espece Alexandrium minutum s'averent comme particulierement dangereuses. Cette espece produit des toxines paralysantes responsables chez l'homme du syndrome PSP ( Paralytic Shellfish Poisoning ). Les incidences des eaux colorees pour les activites economiques se traduisent par des interdictions prefectorales de commercialisation et de ramassage des mollusques filtreurs pouvant entrainer des pertes financieres non negligeables pour les professionnels (ostreiculteurs, mytiliculteurs, . ) ainsi qu'un prejudice sur l'image de marque des zones contaminees pour la frequentation touristique. La presence en France d'Alexandrium minutum dans les eaux cotieres n'a ete signalee que tres recemment : elle a ete observee pour la premiere fois en riviere de Penze en juin 1988 puis dans les abers (Aber Wrac'h et Aber Benoit) en aout 1988. L'espece tend a se disseminer et sa presence a ete relevee ces dernieres annees en Baie de Lannion, dans la Rance et en Baie de Vilaine. Recemment, sa presence a egalement ete signalee dans le bassin de Marennes-Oleron et dans la Rade de Toulon. Les conditions de proliferation de l'espece demeurent encore tres mal connues. Son developpement sur les cotes bretonnes semble restreint aux estuaires et aux baies aquacoles soumis a des apports anthropiques accentues ; l'enrichissement des eaux cotieres en elements nutritifs (azote, phosphore) voire en d'autres especes chimiques (metaux, matieres organiques, . ) pourraient favoriser son developpement jusqu'au stade d'eaux colorees toxiques.
Design Methodology for Single-Feed Circularly Polarized X-Band Antenna Arrays for CubeSats Using Multilevel Sequential Rotation

This article presents a streamlined design methodology for single-feed circularly polarized antenna arrays for CubeSats. The presented method was created with student-led teams in mind and employs a geometrically simple approach, opting for circular patches and ring-shaped feed networks instead of complex geometries. High- and low-impedance radiating elements are designed, and design restrictions are introduced such that all other geometries may be solved through a set of simple cascading equations. These deliberate choices minimize the number of design parameters and simplify the design process. Circular polarization is achieved through a multilevel implementation of sequentially arranged linearly polarized circular patches fed in a series-parallel fashion by ring-shaped feed lines of constant impedance. This article also demonstrates a <inline-formula> <tex-math notation="LaTeX">$4\times 4$ </tex-math></inline-formula> right-hand circularly polarized (RHCP) CubeSat downlink array antenna designed for operation in the 8025–8400-MHz Earth exploration satellite band which was developed using the proposed methodology. The antenna comprises four sequentially rotated RHCP subarrays, each consisting of four sequentially rotated linearly polarized circular patches. The antenna’s boresight RHCP gain exceeds 16.19 dBic at 8.389 GHz with a simulated 27.9% 3-dB axial ratio bandwidth, a 20° half-power beamwidth, and an aperture efficiency of 53%. The antenna has a sub-2 VSWR bandwidth of 26.6%, and its radiation efficiency ranges from 60% to 82% across the target band. Its compact size of 9 cm <inline-formula> <tex-math notation="LaTeX">$\times $ </tex-math></inline-formula> 9 cm enables it to fit on one face of a 10 cm <inline-formula> <tex-math notation="LaTeX">$\times $ </tex-math></inline-formula> 10 cm CubeSat unit.
Interannual Climate Variability of the Past Millennium from Simulations

Abstract The interannual variability of global temperature and precipitation during the last millennium is analyzed using the results of ten coupled climate models participating in the Paleoclimate Modelling Intercomparison Project Phase 3. It is found that large temperature (precipitation) variability is most dominant at high latitudes (tropical monsoon regions), and the seasonal magnitudes are greater than the annual mean. Significant multi-decadal-scale changes exist throughout the whole period for the zonal mean of both temperature and precipitation variability, while their long-term trends are indistinctive. The volcanic forcings correlate well with the temperature variability at midlatitudes, indicating possible leading drivers for the interannual time scale climate change.
Virtual Prototyping of Measurement Setup for Complex Light Scattering Properties

The objects with complex light scattering, for example, light guiding plates with surface and volume microstructures are widely used in modern optical devices and computer graphics. Typically, such properties are described with Bi-Directional Scattering Distribution Function (BSDF) which totally describes the dependence of scattering properties on illumination and observation conditions. The precise BSDF measurements require complex setups with high resolution and launching numerous measurements in the entire angular space. The virtual prototyping of BSDF measurement devices is a difficult and problematic task because of the very small efficiency of similar systems. In the given paper the optimal and more effective ways to simulate such devices are presented based on example of patented scheme for portable BSDF measurements setup, including tolerance calculation and accuracy estimation.
Postoperative Cognitive Impairment and Pain Perception after Abdominal Surgery—Could Immersive Virtual Reality Bring More? A Clinical Approach

Background and Objectives: Impaired cognition and pain after surgery contribute to prolonged hospital stays and increased mortality rates. Thus, the development of preemptive algorithms for reducing their impact should be prioritized. The main objectives of the present study were to evaluate the efficiency of using virtual reality (VR) to treat postoperative cognitive decline and pain perception. Materials and Methods: The study was a prospective, monocentric, clinical study that included 51 patients who have undergone major abdominal surgery. The patients were divided into two groups: Control (n = 25) and VR (n = 26). The VR sessions consisted of 5–8 min exposure at 24–48 h after surgery. We considered the outcome variables, the mini-mental state examination, and visual analogue scale at 24–48 h after surgery. The dependent variables were age, social status, educational level, and duration of surgery. Results: We did not observe any differences in postoperative cognition deficit with regard to VR. The VR, however, successfully reduced postoperative pain intensity. Moreover, the patients’ age, surgery duration, level of education, and social status influenced the MMSE score at 24–48 h after surgery. Conclusions: Even if using VR does not alleviate short-term postoperative cognitive impairments, it could affect pain perception. Further studies are needed to support the use of VR in perioperative contexts.
Adaptation Discourses and Modes of Governance in Swiss Alpine Regions

Like other European countries, Switzerland has started to develop a national climate change adaptation strategy only rather recently. In contrast, Swiss cantonal (i.e., state-level) governments—in particular those in highly vulnerable mountain regions—have been more active in formulating and implementing adaptation measures. These measures, however, differ considerably with respect to scope, range, and mode within and across regions. In this paper, we analyze this variety of regional adaptation measures within the Swiss federalist political system looking specifically at three mountainous cantons in different parts of Switzerland. Particularly, we will try to explain the timely occurrence of these adaptation activities and the governance patterns that emanate from these activities at the regional level. Fur this purpose, we developed a dataset including all public (in the sense of ‘public policy’) adaptation measures in the three selected cantons for the period from 2001 to 2011 based on publicly available documentations such as legal documents, governmental and administrative reports, parliamentary minutes and press releases. The study shows that similar patterns over time in the occurrence of adaptation activities in the three regions can be observed. This similarity seems to be due to a trans-regional adaptation discourse shaped by the national and international policy agenda rather than by specific regional conditions such as the occurrence of locally explicit extreme events. The discussed or applied modes of governance in these adaptation activities, on the other hand, display some significant differences between the three regions. Most adaptation activities are information or research oriented with the cantonal government and its public administration being the main body in charge of the activities. However, the relevant fields of application (policy sectors) clearly reflect the topographical and socio-economic conditions in the three cantons.
Indoor infestations of two imported ant species (Pheidole anastasii Mayr, 1870 and Pheidole punctatissima Emery, 1896) (Hymenoptera, Formicidae) in Norway

During the period 2005–2007 eight indoor infestations of Pheidole (Formicidae) have been reported to the Norwegian Institute of Public Health. One infestation was identified as Pheidole anastasii Emery, 1896 and two as P. punctatissima Mayr, 1870. As to species level, the remaining samples were not identified. All the reported infestations were from cities or near cities in southern Norway. Most likely, the ants were imported with the soil in flower pots.
A Compact Model of FTJ Covering the Trapping/De-trapping Charateristics

Trap effects in the metal-ferroelectric-silicon (MFS) FTJs are modeled in this work. From the charge conservation and voltage balancing principles, traps at the interface between the ferroelectric (FE) layer and silicon are incorporated into the FTJs’ current-voltage characteristics. The trapping/de-trapping dynamics are coupled to the polarizations via a two-state model framework. The electrostatic potentials hence the barriers of tunneling, the trap charge state, and relaxations are all captured. Implications on FTJ operations under different frequencies are discussed around the trap effects on TER.
