Background
Chagas disease, affecting approximately eight million individuals in tropical regions, is primarily transmitted by vectors. Rhodnius prolixus, a triatomine vector, commonly inhabits in ecotopes with diverse palm tree species, creating optimal conditions for vector proliferation. This study aims to explore the transmission ecology of Trypanosoma cruzi, the causative parasite of Chagas disease, by investigating the feeding patterns and natural infection rates of R. prolixus specimens collected from various wild palm species in the Colombian Orinoco region.

Materials and methods
To achieve this objective, we sampled 35 individuals from three palm species (Attalea butyracea, Acrocomia aculeata, and Mauritia flexuosa) in a riparian forest in the Casanare department of eastern Colombia, totaling 105 sampled palm trees. DNA was extracted and analyzed from 115 R. prolixus specimens at different developmental stages using quantitative PCR (qPCR) for T. cruzi detection and identification of discrete typing units. Feeding preferences were determined by sequencing the 12S rRNA gene amplicon through next-generation sequencing.

Results
A total of 676 R. prolixus specimens were collected from the sampled palms. The study revealed variation in population densities and developmental stages of R. prolixus among palm tree species, with higher densities observed in A. butyracea and lower densities in M. flexuosa. TcI was the exclusive T. cruzi discrete typing unit (DTU) found, with infection frequency positively correlated with R. prolixus abundance. Insects captured in A. butyracea exhibited higher abundance and infection rates than those from other palm species. The feeding sources comprised 13 mammal species, showing no significant differences between palm species in terms of blood sources. However, Didelphis marsupialis and Homo sapiens were present in all examined R. prolixus, and Dasypus novemcinctus was found in 89.47% of the insects.

Conclusion
This study highlights the significance of wild palms, particularly A. butyracea, as a substantial risk factor for T. cruzi transmission to humans in these environments. High population densities and infection rates of R. prolixus were observed in each examined palm tree species.

Published: February 2024

AbstractPatients with obstructive sleep apneas (OSA) do not complain from dyspnea during resting breathing. Placement of a mandibular advancement device (MAD) can lead to a sense of improved respiratory comfort (“pseudo‐relief”) ascribed to a habituation phenomenon. To substantiate this conjecture, we hypothesized that, in non‐dyspneic awake OSA patients, respiratory‐related electroencephalographic figures, abnormally present during awake resting breathing, would disappear or change in parallel with MAD‐associated pseudo‐relief. In 20 patients, we compared natural breathing and breathing with MAD on: breathing discomfort (transitional visual analog scale, VAS‐2); upper airway mechanics, assessed in terms of pressure peak/time to peak (TTP) ratio respiratory‐related electroencephalography (EEG) signatures, including slow event‐related preinspiratory potentials; and a between‐state discrimination based on continuous connectivity evaluation. MAD improved breathing and upper airway mechanics. The 8 patients in whom the EEG between‐state discrimination was considered effective exhibited higher Peak/TTP improvement and transitional VAS ratings while wearing MAD than the 12 patients where it was not. These results support the notion of habituation to abnormal respiratory‐related afferents in OSA patients and fuel the causative nature of the relationship between dyspnea, respiratory‐related motor cortical activity and impaired upper airway mechanics in this setting.
On the area-preserving Willmore flow of small bubbles sliding on a domain’s boundary
Authors: Metsch Jan-Henrik 
Published: February 2024

Abstract
We consider the area-preserving Willmore evolution of surfaces ϕ that are close to a half-sphere with a small radius, sliding on the boundary S of a domain Ω while meeting it orthogonally. We prove that the flow exists for all times and keeps a “half-spherical” shape. Additionally, we investigate the asymptotic behavior of the flow and prove that for large times the barycenter of the surfaces approximately follows an explicit ordinary differential equation. Imposing additional conditions on the mean curvature of S, we then establish convergence of the flow.

Function follows Form or Form follows Function – The Legal Nature of CBDC
Authors: Lemke Christina M 
Published: February 2024

Abstract

211Central Bank Digital Currency (CBDC) is often described as the future of money, pictured to function as a new, widely adopted means of payment. Whilst economic and public law implications of CBDC issuance have received close scrutiny, private law issues – especially the question of CBDC’s legal nature – have received little attention. This is surprising, given that the function of money as a means of payment is primarily shaped by the private law framework. So far, this framework is tailored to money’s specific forms of appearance, either as (tangible) property or as (intangible) claims against financial intermediaries. Early research has sought to simply classify CBDC within this dichotomy, according to its design respectively being token or account based. Assuming a German private law point of view, this paper will put such classification to the test as regards the intended “European CBDC”, the digital euro. It will show that the focus on token versus account is misguided and ultimately unhelpful, as the digital euro would in neither form fit within the existing legal framework. Drawing on the discussions surrounding the legal nature of cryptocurrencies and cryptoassets, as well as the recent experience with the dematerialisation of securities, it will be argued that the envisioned dematerialisation of cash offers the opportunity to re-think the legal nature of such new money, based not on its form, but on its function as a circulating means of payment. Putting function before form allows technology-neutral answers to related issues, such as the legal assessment of CBDC transfer, ultimately equipping private law for the future of money.
Submodules of normalisers in groupoid C*-algebras and discrete group coactions
Authors: Komura Fuyuta 
Published: February 2024

Abstract
In this paper, we investigate certain submodules in C*-algebras associated to effective étale groupoids.
First, we show that a submodule generated by normalizers is a closure of the set of compactly supported continuous functions on some open set.
As a corollary, we show that discrete group coactions on groupoid C*-algebras are induced by cocycles of étale groupoids if the fixed point algebras contain C*-subalgebras of continuous functions vanishing at infinity on the unit spaces.
In the latter part, we prove the Galois correspondence result for discrete group coactions on groupoid C*-algebras.
Uniform bounds for Kloosterman sums of half-integral weight with applications
Authors: Sun Qihang 
Published: February 2024

Abstract
Sums of Kloosterman sums have deep connections with the theory of modular forms, and their estimation has many important consequences. Kuznetsov used his famous trace formula and got a power-saving estimate with respect to x with implied constants depending on m and n. Recently, in 2009, Sarnak and Tsimerman obtained a bound uniformly in x, m and n.
The generalized Kloosterman sums are defined with multiplier systems and on congruence subgroups. Goldfeld and Sarnak bounded sums of them with main terms corresponding to exceptional eigenvalues of the hyperbolic Laplacian. Their error term is a power of x with implied constants depending on all the other factors. In this paper, for a wide class of half-integral weight multiplier systems, we get the same bound with the error term uniformly in x, m and n.
Such uniform bounds have great applications. For the eta-multiplier, Ahlgren and Andersen obtained a uniform and power-saving bound with respect to m and n, which resulted in a convergent error estimate on the Rademacher exact formula of the partition function

Controllability result in α-norm for some impulsive partial functional integrodifferential equation with infinite delay in Banach spaces
Authors: Mbainadji Djendode 
Published: February 2024

Abstract
The purpose of this paper is to study the controllability in the α-norm for some impulsive partial functional integrodifferential equation with infinite delay in Banach space. To do this, we give sufficient conditions ensuring the controllability by assuming that the undelayed part admits a resolvent operator in the sense of Grimmer and that the delayed part is continuous with respect to the fractional power of the generator. The results are obtained by using the Schauder fixed-point theorem.
Polynomial convergence of iterations of certain random operators in Hilbert space
Authors: Ghosh Soumyadip , Lu Yingdong , Nowicki Tomasz 
Published: February 2024

Abstract
We study the convergence of a random iterative sequence of a family of operators on infinite-dimensional Hilbert spaces, inspired by the stochastic gradient descent (SGD) algorithm in the case of the noiseless regression.
We identify conditions that are strictly broader than previously known for polynomial convergence rate in various norms, and characterize the roles the randomness plays in determining the best multiplicative constants. Additionally, we prove almost sure convergence of the sequence.

Authors: Erdag Halil Ibrahim , Erzincanli Fehmi , Ocalir Seref 
Published: February 2024

Abstract
In precision casting, many model materials can be used to make complex, accurately sized molds. Model material is an important key for successful production. Wax models are widely used in model manufacturing because they allow economical production. In the wax injection method, some undesirable situations occur during the production of the model such as shrinkage, collapse, warpage, weld marks, surface defects, air marks, and burr formation that the manufacturer does not want. In this study, it is aimed to examine the effect of temperature and pressure parameters on shrinkage of the wax model in injection molding. The study was carried out at wax temperatures of 65 °C, 70 °C, and 75 °C and injection pressures of 0.1 MPa, 0.15 MPa, 0.2 MPa, and 0.25 MPa. In the experiments, the flow of the parts was observed during the filling of the plexiglass mold, and the shrinkage ratio of the obtained wax model was determined and evaluated. It is assigned that some of factors which affect quality of the final product produced by investment casting method are product shrinkage and surface quality of wax model.
Topological hyperbolic metamaterials
Authors: Li Zhitong , Gu Qing 
Published: February 2024

Abstract
Hyperbolic metamaterial (HMM) is a unique type of anisotropic material that can exhibit metal and dielectric properties at the same time. This unique characteristic results in it having unbounded isofrequency surface contours, leading to exotic phenomena such as spontaneous emission enhancement and applications such as super-resolution imaging. However, at optical frequencies, HMM must be artificially engineered and always requires a metal constituent, whose intrinsic loss significantly limits the experimentally accessible wave vector values, thus negatively impacting the performance of these applications. The need to reduce loss in HMM stimulated the development of the second-generation HMM, termed active HMM, where gain materials are utilized to compensate for metal’s intrinsic loss. With the advent of topological photonics that allows robust light transportation immune to disorders and defects, research on HMM also entered the topological regime. Tremendous efforts have been dedicated to exploring the topological transition from elliptical to hyperbolic dispersion and topologically protected edge states in HMM, which also prompted the invention of lossless HMM formed by all-dielectric material. Furthermore, emerging twistronics can also provide a route to manipulate topological transitions in HMMs. In this review, we survey recent progress in topological effects in HMMs and provide prospects on possible future research directions.

Kostenwahrheit und Kostenscheinwahrheit: Eine politisch-ökonomische Analyse
Authors: Stadelmann David , Eichenberger Reiner 
Published: February 2024

Abstract
Ökonomen vertreten Kostenwahrheit im Sinne einer angemessenen Bepreisung negativer externer Effekte, weil sie die Handelungsträger motiviert, die von ihnen verursachten externen Effekte in ihrem wirtschaftlichen Handeln zu berücksichtigen. Aus politisch-ökonomischer Sicht ist Kostenwahrheit sogar noch wichtiger. Sie motiviert die politischen Handlungsträger die gesellschaftlichen Kosten ihres politischen Handelns zu berücksichtigen und die externen Kosten genauer zu erfassen als bei alternativen Politikmaßnahmen wie Geboten oder Verboten. Doch gerade wegen ihrer Vorteile setzt sich Kostenwahrheit im politischen Prozess selten vollständig durch. Denn sie verengt den Spielraum von Politikern, sich und den ihnen nahestehenden Interessengruppen wirtschaftliche und politische Renten zu verschaffen. Zugleich wird das Konzept der Kostenwahrheit missbraucht, um nur »Kostenscheinwahrheit« und neue Renten zu schaffen. Entscheidend ist daher, echte Kostenwahrheit durch geeignete institutionelle Regelungen abzusichern.
Characterization and comparison of cobalt-base and nickel-base alloys with iron-base intermetallic hard alloys used in wear protection
Authors: Friederichs S. , Lorenz S. 
Published: February 2024

Abstract
In wear protection, cobalt-base or nickel-base materials are very often used for coatings in order to increase the functionality and service life of components. These materials such as stellite, the nickel-base alloy Colmonoy 56 or Tribaloy T400 are characterized by a high resistance to abrasion, adhesion as well as excellent corrosion resistance even at higher temperatures.
Given the criticality of cobalt and partly also nickel, it is necessary to look for more sustainable alternatives to be used in wear protection. One possibility is to further develop iron-base materials so that they can be used in wear protection to prevent both abrasion and adhesion. In this context, sufficient corrosion resistance is desirable. This paper will elaborate on the development of a novel intermetallic iron-base hard alloy.
Discoloration on Laser Welds of AISI 321 Tubes
Authors: Neidel A. , Rockel J. , Riesenbeck S. 
Published: February 2024

Abstract
In this contribution, a fabrication problem is discussed, related to Laser Beam Welding (LBW). Strictly speaking, the case study presented herein does not constitute a failure as such, since the subject components never made it to component service. In the narrow sense of the word, a component failure happens if and when a part does no longer serve its proper function. This is definitely not the case in the study put forward in this paper. However, one could argue that a product that cannot be marketed for lack of certain properties, or because of certain shortcomings, is rendered worthless for the manufacturer and this, in turn, could be considered a failure. In this case study, the issue of discoloration on the surfaces of welded austenitic stainless steel is discussed. This is a well-known and well-researched fabrication problem. Dependent upon service conditions of affected parts, discoloration might be detrimental to the normally outstanding corrosion resistance of this class of high-alloy steels.
Основні етапи формування євроінтеграційного курсу України та Молдови: порівняльна характеристика
Authors: Вуйко Анастасія 
Published: February 2024

Актуальність. В умовах військового стану, в якому перебуває Україна та спільних з Молдовою геополітичних безпекових викликів, надзвичайно важливою є підтримка ЄС. Досвід російсько-української війни доводить, що лише спільні скоординовані дії демократичних держав здатні впливати на геополітичні безпекові виклики, а також пришвидшити вступ до ЄС. Для розробки подальшого скоординованого плану дій держав-сусідів України та Молдови у євроінтеграційному політичному курсі, надзвичайно важливо проаналізувати фундамент євроінтеграційного курсу обох країн.
Метою дослідження є здійснення порівняльного дослідження основних етапів формування євроінтеграційного політичного курсу України та Республіки Молдова з моменту проголошення незалежності й до початку повномасштабного вторгнення росії в Україну.
Результати. Здійснено та представлено порівняльну характеристику основних етапів формування євроінтеграційного політичного курсу України та Республіки Молдова на основі аналізу зовнішніх та внутрішніх чинників, й геополітичних суперечностей, що вплинули на євроінтеграційні процеси обох країн.
Висновки. Зважаючи на динаміку розвитку євроінтеграційних процесів в обох країнах, ключові події на кожному з етапів формування євроінтеграційного політичного курсу відбувалися майже одночасно, але протягом останніх тридцяти років країни мали різні періоди у двосторонніх відносинах.
З початком повномасштабного вторгнення росії в Україну 24 лютого 2022 року розпочався новий етап у відносинах України та Молдови з Брюсселем. Війна в Україні та змінний безпековий ландшафт відкрили вікно можливостей для України та Молдови, змусивши ЄС швидко розглянути подані заявки на членство.
Попереду в України та Молдови робота над «домашніми завданнями» та здійсненням відповідних реформ для подальшого вступу в ЄС. Проте, рік російсько-української війни, з усіма її наслідками, наочно показав не лише лідерам країн ЄС, а й всьому світу важливість єдності і прийняття швидких рішень довкола спільної небезпеки.

The research was carried out on 3 apple varieties, namely Golden delicious, Jonathan and Starkrimson, grown in the N-E area of Romania, within the Research Station for fruit growing Iasi, on Fălticeni development center. The plantation was established in 1990, being in 31 since planting. The trees are grafted on the MM106 rootstock, with a planting distance of 4 meters between rows and 2.5 meters between trees, with a density of 1000 trees/ha. During the agricultural year 2021, hail was observed as an extreme climatic phenomenon, recorded in June, July and August, when the trees were in the phenological stage BBCH 71-74, BBCH 75, BBCH 77 and BBCH 79. Extreme phenomena were accompanied by heavy rains and storms that affected both the quality and quantity of fruit production. The highest degree of damage was recorded in the Golden delicious variety in all four hail falls, with a percentage between 5% and 67%. Therefore, the fruit production was affected, their quality being impaired and not being commercialized as high quality fruit, for fresh consumption, but only industrialized.
Patentable Formula Based on Essential Oils with a Protective Effect Against Rhizobium Vitis
Authors: DINU Sorina , BARBU Lavinia-Diana-Nicoleta , CHIRECEANU Constantina 
Published: February 2024

The crown gall of grapevines is an economic importance bacteriosis caused by Rhizobium vitis strains. Five essential oils (EO’s) were tested against the autochthonous 2btm strain of R. vitis for their capacity to inhibit the phytopathogen growth, by in vitro and in planta tests. The measurements regarding in vitro inhibition zone were performed. Subsequently, the ability of patentable formula based on essential oils to prevent/reduce tumor formation in tomato and vine plants has been tested. After 30 days for tomato plants, the evaluation of disease incidence and effectiveness of treatments applied at two points in time (T0 and T30), were determined. In vine plants, tumorigenesis is initiated up to 9 months after inoculation, so the results are being processed. Efficacy values of 94.7% at both T0 and T30 and, a very low disease incidence of 5% compared to positive control were recorded. Also, the tumor of EO’s treated tomato plants were smaller in size and did not form a complete ring as positive control plants. The use of patentable formula as prevented treatment, reduced the number of plants developing crown gall symptoms and tumor size compared to positive control plants.
