A Safe and Fast Repulsion Method for GPU-based Cloth Self Collisions
Authors: Wu Longhua , Wu Botao , Yang Yin , Wang Huamin
Published: December 2020

Cloth dynamics and collision handling are the two most challenging topics in cloth simulation. While researchers have substantially improved the performances of cloth dynamics solvers recently, their success in fast collision detection and handling is rather limited. In this article, we focus our research on the safety, efficiency, and realism of the repulsion-based collision handling approach, which has demonstrated its potential in existing GPU-based simulators. Our first discovery is the necessary vertex distance conditions for cloth to enter self intersections, the negations of which can be viewed as vertex distance constraints continuous in time for sufficiently avoiding self collisions. Continuous constraints, however, cannot be enforced with ease. Our solution is to convert continuous constraints into three types of constraints: discrete edge length constraints, discrete vertex distance constraints, and vertex displacement constraints. Based on this solution, we develop a fast and safe collision handling process for enforcing constraints, a novel splitting method for integrating collision handling with dynamics solvers, and static and adaptive remeshing schemes to further improve the runtime performance. In summary, our cloth simulator is efficient, safe, robust, and parallelizable on a GPU. The experiment shows that it runs at least one order of magnitude faster than existing simulators.

Authors: Liang Chao , Zhang Jing , Liu Yongqian , Yan Jie , He Wei
Published: December 2020

To achieve a high penetration of renewable energy, wind power development in China has gradually moved to diverse manifestation (e.g., centralized onshore, low wind speed, and offshore wind power). However, preexisting studies regarding wind power cost neglect to consider the respective characteristics of different development scenarios. In this paper, the overall levelized cost of energy (OLCOE) model is established for different scenarios. Taking China’s wind farm data as an example, the impact of development scenarios and wind power permeability on OLCOE and its cost components is quantitatively analysed. The results show that, (1) in the low penetration scenario, low wind speed power has the best economy and is beneficial to the conventional units; (2) the large-scale development of offshore wind power requires a reduction in the cost of offshore wind turbines and submarine cables; and (3) at present, onshore centralized wind power has economic advantages, but there is little room for its cost reduction.

Published: December 2020

When an underground rock is deformed or fractured by an external or internal force, the energy will be released in the form of an elastic wave, which is known as the acoustic emission (AE) phenomenon. Extracting useful information from complex AE signals for the early warning of fracture characteristics and the damage monitoring of rock materials is of great significance for the prevention and control of dynamic disasters in coal mines. In this work, by taking rod‐shaped rocks and plate‐shaped rocks with different lithologies as the research objects, the elastic wave propagation characteristics of the rod‐shaped rocks and plate‐shaped rocks were studied by a self‐constructed experimental platform. The results demonstrate that the elastic wave attenuation of the rod‐shaped marble was the fastest, and the elastic wave attenuation characteristics of the three groups of rod‐shaped granite were similar. The attenuation of the P‐wave preceded that of the S‐wave. With the increase in the propagation distance, the amplitude of the large‐scale plate‐shaped rock showed an approximate exponential attenuation characteristic. The elastic wave attenuation of the plate‐shaped granite in the 0° direction was stronger than that of the plate‐shaped marble, and it was weaker than that of the plate‐shaped marble in the 45° and 90° directions. The energy changes in marble were more severe than those in granite. The main dominant energy of the AE signals of experimental rock was concentrated in the range of 0–176.78 kHz, and part of the residual energy was located in the high‐frequency band of 282.25–352.56 kHz.

Published: December 2020

Beetles have excellent flight performance. Based on the four-plate mechanism theory, a novel bionic flapping aircraft with foldable beetle wings was designed. It can perform flapping, gliding, wing folding, and abduction/adduction movements with a self-locking function. In order to study the flight characteristics of beetles and improve their gliding performance, this paper used a two-way Fluid-Structure Interaction (FSI) numerical simulation method to focus on the gliding performance of the bionic flapping aircraft. The effects of elastic model, rigid and flexible wing, angle of attack, and velocity on the aerodynamic characteristics of the aircraft in gliding flight are analyzed. It was found that the elastic modulus of the flexible hinges has little effect on the aerodynamic performance of the aircraft. Both the rigid and the flexible wings have a maximum lift-to-drag ratio when the attack angle is 10°. The lift increased with the increase of the gliding speed, and it was found that the lift cannot support the gliding movement at low speeds. In order to achieve gliding, considering the weight and flight performance, the weight of the microair vehicle is controlled at about 3 g, and the gliding speed is guaranteed to be greater than 6.5 m/s. The results of this study are of great significance for the design of bionic flapping aircrafts.

Background and Aim. Appendicitis is unusual in toddlers and foreign body- (FB-) induced appendicitis is rare. We present a FB-induced appendicitis in a toddler with no suggestive history of FB ingestion. Case Presentation. A 2-year-old healthy boy presented to the emergency department with irritability for 3 days duration associated with fever of 39°C, nausea, anorexia, and vomiting. There was no history of foreign body ingestion. The abdomen was distended and diffusely tender. An abdominal ultrasound (US) was suggestive of perforated appendicitis with appendicular mass formation. An abdominal X-ray showed a pin-like foreign body in the abdomen. An emergent appendectomy was performed. Intraoperatively, a sealed small cecal perforation was noticed. A 5 cm pin-like metallic foreign body was found to obstruct the appendicular lumen. The appendix was grossly normal without inflammatory changes. Conclusion. FB-induced perforations or appendicitis albeit in patients with no history of FB ingestion or infants and toddlers need a high clinical suspicion to prevent the delay in diagnosis and the subsequent complications.

Published: December 2020

A substantial amount of research is being conducted on zonation markers to identify hepatic injuries and disorders based on the structural and functional zonation of the liver. In contrast to metabolic zonation, hepatocyte ploidy reflects the capability of liver regenerative turnover. Nonetheless, many knowledge gaps remain in the understanding of the links between liver disorders and altered zonation and ploidy, partially owing to the lack of sufficient zonation markers. Under this setting, we recapitulated the currently known and prospective markers used to identify normal and altered liver zonation in different disorders. Furthermore, we discussed new findings from studies that have used advanced methodologies to identify potential markers with greater accuracy. We also elaborated on the perspectives and future applications of zonation research in the early detection of various liver diseases.

Authors: Kumar Hemant , Singh Mangej
Published: December 2020

Cadmium Selenide (CdSe) thin films have been deposited on a cleaned glass substrate by thermal vacuum evaporation method under the pressure of 10-5 torr. These CdSe thin films were also kept into a quart glass tube for rapid thermal annealing at 60 and 120 second using a
500 W halogen lamp for crystalline the structure. These thin films were characterized for structural, optical and thermo-electrical properties. The optical studies have been done using UV-VIS-NIR, shows that the transition of the deposited film is found to be a direct band gap of 1.74, 1.70
and 1.67 eV for asdeposited, 60 sec and 120 sec annealed thin films respectively. It was also found that absorbance has increased and transmission decreased with increasing annealing time, the change in the extinction coefficient with energy (hν) has been also measured. The Thermoelectric
power (TEP) studies confirm the n-type nature of CdSe thin films but as well as annealing time increased the hole concentration increased resultant n-nature of CdSe thin film changing toward p-type nature, the Seebeck coefficient for different annealing time at as-deposited
(RT), 60 seconds and 120 seconds have observed 549, 949 and 1031 μV/K respectively. The SEM result shows that with increasing annealing time the grain size and roughness of surface are increased. X-ray diffraction (XRD) studies indicate that the film is like a cubic crystal structure with
average crystalline size (D) was measured using Scherrer formula and it is 16.44 nm.
Design of a Near Field Communication-Enabled Points Collection Application System
Authors: Yang Jui-Pin
Published: December 2020

Nowadays, users collect points by stickers after they purchase products. However, to issue stickers and to exchange points are inconvenient to store staffs and users. In addition, the traditional way for points collection increases the business cost because of additional cards and stickers.
In this paper, we propose a novel, practical and integrated application system to resolve above issues namely NFC-enabled Point Collection Application System (NPCAS). NPCAS mainly consists of three subsystems including user-side APP, store-side APP and backend management system. The user-side
APP let users to quickly complete points management, for instance, they can accumulate points by communicating with the store-side APP through Near Field Communication (NFC) technique. The store-side APP calculates the points of each transaction and updates them to the backend management system.
Then, the users can inquire their current points, exchange details, exchangeable commodities and so on. Android operating system is the mainstream on smart phones so that the Android-based APPs attract a lot of attention. Accordingly, we develop both APPs based on Java, XML, Android Software
Development Kit (SDK) and Android Studio. The backend management system is built by Apache server, PHP module, PHP files and MySQL database. The format that we used on information exchange between backend management system and both APPs is JavaScript Object Notation (JSON). In a word, NPCAS
greatly simplifies the procedures of points collection and management.

Authors: Pennington Kaylin , Harwood Eileen , Sick Brian
Published: December 2020

Introduction

Community-based student-run free clinics (SRCs) can advance health on a community level by reaching populations not served by other organizations and serving as an access point to the healthcare system. However, little is known about the scope of community-engaged efforts undertaken by SRCs, including interorganizational partnerships and relationship-building activities. The primary objective of this study was to characterize the community collaborations of an interprofessional SRC located in a high-poverty area.

Methods

Qualitative data was collected through semi-structured interviews with key stakeholders, which included student volunteers holding leadership roles, representatives of community-based organizations, and current and former members of the community advisory board.

Results

Key informant interviews with student and community leaders offered insight into local community outreach activities and the community advisory board. Findings revealed opportunities to impact community health through more intentional collaboration and relationship-building.

Conclusions

This exploratory study adds to literature suggesting that community-based SRCs can address service gaps in medically underserved communities while advancing community health through intentional community engagement.
Fasting Glucose Variation Predicts Microvascular Risk in ACCORD and VADT
Authors: Zhou Jin J , Koska Juraj , Bahn Gideon , Reaven Peter
Published: December 2020

Aims

The association of glycemic variability with microvascular disease complications in type 2 diabetes (T2D) has been under-studied and remains unclear. We investigated this relationship using both Action to Control Cardiovascular Risk in Diabetes (ACCORD) and the Veteran Affairs Diabetes Trial (VADT).

Methods

In ACCORD, fasting plasma glucose (FPG) was measured 1 to 3 times/year for up to 84 months in 10 251 individuals. In the VADT, FPG was measured every 3 months for up to 87 months in 1791 individuals. Variability measures included coefficient of variation (CV) and average real variability (ARV) for fasting glucose. The primary composite outcome was time to either severe nephropathy or retinopathy event and secondary outcomes included each outcome individually. To assess the association, we considered variability measures as time-dependent covariates in Cox proportional hazard models. We conducted a meta-analysis across the 2 trials to estimate the risk of fasting glucose variability as well as to assess the heterogenous effects of FPG variability across treatment arms.

Results

In both ACCORD and the VADT, the CV and ARV of FPG were associated with development of future microvascular outcomes even after adjusting for other risk factors, including measures of average glycemic control (ie, cumulative average of HbA1c). Meta-analyses of these 2 trials confirmed these findings and indicated FPG variation may be more harmful in those with less intensive glucose control.

Conclusions

This post hoc analysis indicates that variability of FPG plays a role in, and/or is an independent and readily available marker of, development of microvascular complications in T2D.

Authors: Weider Therese , Richardson Sarah J , Morgan Noel G , Paulsen Trond H , Dahl-Jørgensen Knut , Hammerstad Sara Salehi
Published: December 2020

Context

The origin of Graves disease (GD) remains elusive. However, evidence of an association between GD and viral infections is emerging. Human leukocyte antigen (HLA) class I presents viral antigens to circulating immune cells and plays a crucial role in the defense against viral infections.

Objective

This work aimed to investigate HLA class I expression, enterovirus presence, and the viral immune response proteins signal transducer and activation of transcription 1 (STAT1) and protein kinase R (PKR) in thyroid tissue from GD patients.

Methods

We collected thyroid tissue from core needle biopsies or surgical specimens from 48 GD patients and 24 controls. Standard immunohistochemistry was used to detect HLA class I and enteroviral capsid protein 1 (VP1) on formalin-fixed and paraffin-embedded tissue. STAT1 and PKR were examined by combined immunofluorescence staining. HLA class I expression score was the main outcome measure.

Results

The HLA class I expression score, which takes both proportion and intensity of immunostaining into account, was significantly higher in GD patients (3.1 ± 3.3) than in controls (0.5 ± 0.9) (P < .001). Significantly more VP1 positive thyroid cells were found GD samples (50.1 ± 30.5%) than in controls (14.9 ± 10.5%) (P < .001). STAT1 and HLA class I were found within the same thyroid cells and PKR and VP1 were also colocalized within thyroid cells.

Conclusion

HLA class I is upregulated in GD and enterovirus protein is prevalent in thyroid tissue. The colocalization of HLA class I with STAT1 and VP1 with PKR indicates an antiviral tissue response. These findings support the concept of a link between viral infections and GD.

A correct biosynthetic activity is thought to be essential for the long-term function and survival of islet cells in culture and possibly also after islet transplantation. Compared to the secretory activity, biosynthetic activity has been poorly studied in pancreatic islet cells. Here we aimed to assess biosynthetic activity at the single cell level to investigate if protein synthesis is dependent on secretagogues and increased as a consequence of hormonal secretion. Biosynthetic activity in rat islet cells was studied at the single cell level using O-propargyl-puromycin (OPP) that incorporates into newly translated proteins and chemically ligates to a fluorescent dye by “click” reaction. Heterogeneous biosynthetic activity was observed between the four islet cell types, with delta cells showing the higher relative protein biosynthesis. Beta cells protein biosynthesis was increased in response to glucose while 3-isobutyl-1-methylxanthine and phorbol-12-myristate-13-acetate, 2 drugs known to stimulate insulin secretion, had no similar effect on protein biosynthesis. However, after several hours of secretion, protein biosynthesis remained high even when cells were challenged to basal conditions. These results suggest that mechanisms regulating secretion and biosynthesis in islet cells are different, with glucose directly triggering beta cells protein biosynthesis, independently of insulin secretion. Furthermore, this OPP labeling approach is a promising method to identify newly synthesized proteins under various physiological and pathological conditions.
Exploring Novel Catalysis Using Polymer-Stabilized Metal Clusters
Authors: Hasegawa Shingo , Tsukuda Tatsuya
Published: December 2020

Metal clusters composed of no more than one hundred metal atoms have the potential to exhibit novel catalysis that is unexpected from the corresponding bulk and nanoparticles. The emergence of cluster-specific properties is ascribed to the quantized electronic structures, unique geometrical packing, and structural fluxionality. Polymer-stabilized metal clusters provide ideal platforms for exploring new catalysis based on the chemical properties of naked model clusters and studying the correlation between structural parameters and intrinsic catalytic properties of metal clusters. In this article, we describe our recent efforts to explore novel catalysts using polymer-stabilized metal clusters.

Heuristic methods and performance bounds for photonic design
Authors: Angeris Guillermo , Vučković Jelena , Boyd Stephen
Published: December 2020

In the photonic design problem, a scientist or engineer chooses the physical parameters of a device to best match some desired device behavior. Many instances of the photonic design problem can be naturally stated as a mathematical optimization problem that is computationally difficult to solve globally. Because of this, several heuristic methods have been developed to approximately solve such problems. These methods often produce very good designs, and, in many practical applications, easily outperform ‘traditional’ designs that rely on human intuition. Yet, because these heuristic methods do not guarantee that the approximate solution found is globally optimal, the question remains of just how much better a designer might hope to do. This question is addressed by performance bounds or impossibility results, which determine a performance level that no design can achieve. We focus on algorithmic performance bounds, which involve substantial computation to determine. We illustrate a variety of both heuristic methods and performance bounds on two examples. In these examples (and many others not reported here) the performance bounds show that the heuristic designs are nearly optimal, and can be considered globally optimal in practice. This review serves to clearly set up the photonic design problem and unify existing approaches for calculating performance bounds, while also providing some natural generalizations and properties.

Published: December 2020

Background and Aim: Veterinary health care is an emergent area in animal sciences and innovative therapeutic approaches happen to be imperative in the present days. In view of the importance of cattle health and production, it is necessary to take up contemporary approach of stem cell therapy in this sector also. This study aimed to standardize an explant culture method of bovine umbilical tissue offcut to isolate mesenchymal stem cells (MSCs) because considerable efforts are required for ensuring easy accessibility and availability of MSCs in bulk quantity, as well as in establishing and characterizing the cell lines.

Materials and Methods: The umbilical cord (UC) tissue matrix offcut was collected after calving. A simplified in vitro cell isolation technique was followed to collect the emerged out cells from the explants of UC. Further, we expanded these isolated cells in vitro, observed its growth kinetics, and characterized to confirm as per the criterion of bovine MSCs.

Results: A considerable exponential growth rate of the UC-derived cells was noticed. In addition to their confirmation as MSCs, the cells also exhibited plastic adherent property and maintained the spindle-shaped morphology throughout the in vitro culture. The cultured cells were found positive MSC-specific surface markers CD105, CD90, and CD73 and were negative for hematopoietic cell marker CD45. Cytochemical studies revealed the ability of the cells to differentiate into osteogenic, chondrogenic, and adipogenic lineages.

Conclusion: This simplified method of isolation and culture of bovine multipotent MSCs from the UC offcut collected after calving could be extrapolated for the greater availability of the cells for prospective therapeutic applications.

The tectonic nature of the fields of the Nepa-Botuoba anteclise is considered within the framework of the fluid-dynamic concept. The main element of this concept is basin-forming activated fault systems with the properties of cyclic manifestation, direction of generation, time and period of activation. It has been established that deposits in the Vendian terrigenous section at the Chayandа oil and gas condensate field were formed under the influence of an activated fault system of the early northeastern generation.The hydrocarbons accumulations in carbonate strata of the Lower Cambrian in the neighboring Talakan oil and gas condensate field under the influence of the system of late northwestern generation are discordant to each other. According to a number of the considered criteria related to the tectonic nature, the prospects of oil and gas potential of the Vendian-Lower Cambrian carbonate strata on the territory of the Chayandа field are assessed as low. For terrigenous rocks of the Vendian basal strata, the features of the accumulation in the Khamakin productive level in comparison with the Botuobа are established. Assumptions about the underlying source of subvertical fluid flows of hydrocarbons are argued. It is proposed to study the "basement" unit of the Upper Proterozoic in order to increase the hydrocarbons resource base of the field.

For the South-Eastern regions of the West Siberian oil and gas province, a model of the structure of the Bazhenov reservoir and criteria for selecting areas that are promising for detecting oil accumulations in the productive level of the South-West Bazhenov Formation are proposed. According to the our criteria, the following characteristics of the object of research are given: the thickness of rocks of the Bazhenov Formation, the thickness of rocks with a Corg content > 7%, catagenesis degree of organic matter, the thickness of the underlying and overlying fluid barriers, current reservoir temperatures of rocks and reservoir pressures in the Bazhenov Formation. Based on a comprehensive analysis of the materials that characterize the above criteria, promising zones of two categories are identified. The Central-Nyurol zone is assigned to the 1st category (the most promising), and the North-Nyurol, East-Nyurol, South-Nyurol, West-Parabel, and Ust-Tym zones are assigned to the 2nd category.

Seismogeological models of sedimentary stratum on the continent and in the water area are considered; the conclusion was made that the Northern Siberian and Laptev Sea basins are separated by a large basement high that extends from the Taimyr Peninsula along the coastline to the Lena River issue. A complex analysis of geological and geophysical data made it possible to conclude that the most probable model is that the western part of the Laptev Sea is a continuation of the Siberian Platform with an Archaean-Proterozoic basement and an Upper Proterozoic-Phanerozoic sedimentary cover.

Paleomagnetic determinations for the Devonian strata of the Main Devonian Field, available in the international paleomagnetic data base, do not make it possible to construct both detailed magnetostratigraphic scales and reliable trajectories of the apparent polar wander path of the paleomagnetic pole. This is primarily due to the insufficient amount of data that determine modern reliability criteria. Obtaining more complete series of reliable paleomagnetic determinations is one of the important tasks of paleomagnetic studies. The paper presents new paleomagnetic determinations from a collection of rocks of the Frasnian stage of the Upper Devonian (Ilmen and Bureg Beds of the Semiluky Formation), sampled on the southern shore of Lake Ilmen, east of the village. Korostyn in 2009. Magnetomineralogical studies were carried out to determine the magnetic minerals of carriers of natural remanent magnetization. Three characteristic components of natural remanent magnetization have been identified. Two components correspond to the Late Paleozoic magnetization reversal (in the Carboniferous and Permian times). The third, bipolar component of the Frasnian age passes the reverse polarity test of the geomagnetic field.. The obtained position of the paleomagnetic pole by the bipolar component of the natural remanent magnetization is consistent with the available data on the section of the Late Upper Devonian of the Main Devonian Field.

Endüstriyel gelişmelere bağlı olarak birçok sanayide ve yüzey sularında kullanılan bor bileşiklerinin konsantrasyonu artmaktadır. Bu nedenle bor giderimi hem insan sağlığı hem de sağlıklı tarım ürünü yetiştirilebilmesi açısından oldukça önemlidir. Bu çalışmada, kabak çekirdeği kabuğunun adsorpsiyon kapasitesi araştırılmıştır. Çalışma için, çözeltinin pH‘sının, kabak çekirdeği kabuğu konsantrasyonlarının ve temas süresinin adsorpsiyon sürecine etkisi sabit bir karıştırma hızı (150 rpm) ve sıcaklığı (20 0C) altında değerlendirilmiştir. Ayrıca, kabak çekirdeği kabuğu, taramalı elektron mikroskobu, X ışını floresansı ve Fourier dönüşümü kızılötesi teknikleri kullanılarak tanımlanmıştır. Elde edilen deneysel veriler kesikli proseste farklı izoterm ve kinetik modelleri kullanılarak analiz edilmiştir. Adsorpsiyon işlemi için optimum koşullar adsorbent dozu = 2 g/L, pH = 5.13 ve temas süresi = 5 dakika olarak belirlenmiştir. Kabak çekirdeği kabuğunun maksimum bor arıtma verimi, ideal şartlarda yaklaşık % 88 olarak elde edilmiştir. Langmuir izotermine dayalı maksimum adsorpsiyon kapasitesi 12.61 mg/g şeklinde olup bor elementinin kabak çekirdeği kabuğu üzerine adsorpsiyonu yalancı ikinci derece kinetik ile tanımlanmıştır. Sonuç olarak, bor elementinin, kabak çekirdeği kabuğu kullanılarak sulu çözeltiden etkili bir şekilde çıkarılabileceği kaydedilmiştir.
Jeofizik Verilerinden Elde Edilen Sismik Zayıflık İndisinin Yapı Hasar Dağılımının Belirlenmesinde Kullanılabilirliği
Authors: AKKAYA İsmail

Jeofizik yöntemlerden biri olan mikrotremor yönteminin mühendislik uygulamalarındaki kullanımı gün geçtikçe artmaktadır. Mikrotremor verilerinin spektral oranından elde edilen zemin hakim titreşim periyodu ve büyütme değerleri kullanılarak sismik zayıflık indisi (Kg) hesaplanabilmektedir. Kg zemin dinamik özelliklerine bağlı olarak değişen bir parametredir. Bu parametre ile bir alanın kuvvetli yer hareketine karşı dayanıklı veya zayıf kalma durumunun noktasal olarak değerlendirilmesi yapılabilmektedir. Çalışmada, Van yerleşim alanında 220 noktada mikrotremor ölçümleri alınarak yerleşim alanı için zayıflık indisi haritası oluşturulmuştur. Özellikle Van Gölüne yakın kesimlerde ve yapı yoğunluğunun olduğu merkez bölgelerde tehlike düzeyinin ve sismik zayıflık indisinin yüksek olduğu belirlenmiştir. 2011 Van depremi (Mw=7.1) sonrası bölgede incelenen binaların hasar durumları oluşturulan zayıflık indisi haritasına yerleştirilmiş ve yapıların hasar durumlarının zayıflık indeksi ile ilişkili olabileceği gözlenmiştir. Çalışma alanında özellikle Van Gölüne yakın kesimlerinde hem gevşek-suya doygun zemin yapısı hem yapı kalitesi hemde yüksek Kg değerlerinin elde edilmesi olası büyük bir depremde ortaya çıkabilecek yüksek ivme değerlerinde makaslama deformasyonu seviyesine bağlı zemin davranışının hasara neden olan plastik davranış ve göçme davranışına dönüşebileceği tespit edilmiştir. Elde edilen bulgular yapısal hasarlarda yapı kalitesinin yanı sıra zemin tabakalarının dinamik davranışlarının ve yerel zemin koşullarının da etkili olduğunu bir kez daha ortaya koymuştur.

According to the generally accepted view, sensory excitation in the spinal nerve system reaches the spinal cord through the nerve cells of the dorsal nodes, which from this point of view with full right can be attributed to the category of sensitive nerve cells. Working in the early 90s on the issue of negative fluctuations, Steinach came across a fact that remained completely inexplicable for him until the last day.
Monestiev. Contribution to the study of suicide in general paralysis. — Medico-psychological annals. March- April, 1900
Authors: Toporkov N.
Published: December 2020

The author says, quoting Magnan, that in progressive paralysis there are two different diseases: 1. paralytic dementia, the main disease, which is a long-term, continuous disease, has a fatal tendency; it represents certain disorders, known persistent symptoms; 2. madness, which seems to be changeable, transient; most often it depends on congestion and represents the most opposite manifestations. But, despite this variety of manifestations, dementia and disorderly, transient nature of delirium give this madness a peculiar imprint. For example, it is difficult to confuse criminal acts committed by paralytics with those in which the culprit is the mentally ill, but not paralytics. The same applies to attempts at suicide, in which you will encounter a little persistence and childish character of ideas that induce them to these attempts.

Not more than 20 years have passed since then, as the first attempts were made to apply the experimental method to the study of the association of ideas. The first researchers in this area (Galton, Travtscholdt, Catell) were mainly engaged in the speed of associations, working with the help of the well-known Ніррs chronoscope. Then we moved on to the study of the self-content of the associations.
