Case report of mucha-habermann disease
Pityriasis lichenoides et varioliformis acuta (PLEVA), also known as a Mucha-Habermann disease, is an uncommon, idiopathic, and acquired dermatosis. The disease is characterized by erythematous, scaly, papules, and polymorphic lesions which often progresses to hemorrhagic necrosis and heals with varioliform scarring. A febrile ulceronecrotic variant of PLEVA, also termed pityriasis lichenoides (PL) with ulceronecrosis and hyperthermia (PLUH) or febrile ulceronecrotic Mucha-Habermann disease (FUMHD), is a severe variant of PLEVA. The disease is characterized by the acute onset of large, more destructive, coalescent papules, leading to ulceronecrotic skin lesions associated with high fever and other systemic symptoms. In spite of the presence of multiple treatment modalities with variable success rate, the disease has poor prognosis. Here, we report the case of a 17-year-old male patient who presented with typical features of FUMHD and responded well to systemic administration of corticosteroid therapy
Learning Subgrid-Scale Models in Discontinuous Galerkin Methods with Neural Ordinary Differential Equations for Compressible Navier--Stokes Equations
The growing computing power over the years has enabled simulations to become
more complex and accurate. However, high-fidelity simulations, while immensely
valuable for scientific discovery and problem solving, come with significant
computational demands. As a result, it is common to run a low-fidelity model
with a subgrid-scale model to reduce the computational cost, but selecting the
appropriate subgrid-scale models and tuning them are challenging. We propose a
novel method for learning the subgrid-scale model effects when simulating
partial differential equations using neural ordinary differential equations in
the context of discontinuous Galerkin (DG) spatial discretization. Our approach
learns the missing scales of the low-order DG solver at a continuous level and
hence improves the accuracy of the low-order DG approximations as well as
accelerates the filtered high-order DG simulations with a certain degree of
precision. We demonstrate the performance of our approach through
multidimensional Taylor--Green vortex examples at different Reynolds numbers
and times, which cover laminar, transitional, and turbulent regimes. The
proposed method not only reconstructs the subgrid-scale from the low-order
(1st-order) approximation but also speeds up the filtered high-order DG
(6th-order) simulation by two orders of magnitude.Comment: 15 figures, 2 tables, 22 page

Mykola Khvylovy and the Ukrainian renaissance
This thesis examines the 1917 to 1920 Ukrainian Revolution, literary activity in post-Revolutionary Ukrainian, and the works of the eminent Ukrainian writer, Mykola Khvylovy in order to better understand how a short-lived Ukrainian cultural and literary renaissance took shape and how it was suppressed by the Communist Party. My paper is divided into three major parts, which address the Ukrainian Revolution, policies of the Soviet state regarding Ukrainian cultural and literary development, and the literary works of Mykola Khvylovy. In my first three chapters I undertake a fairly detailed analysis of the Ukrainian Revolution. Due to the complexity of the topic, I have divided it into three parts. In these three chapters, I explore the ways in which the Ukrainian intelligentsia sought to establish an autonomous Ukrainian state and how their attempts to create their own vision of an independent Ukraine were ultimately thwarted by foreign aggressions. Despite the utter chaos that characterized the Revolutionary era, the Ukrainian intelligentsia sought to establish a sovereign Ukrainian state. In chapter four, I examine the Soviet policy of Ukrainianization and its ideological antecedents in order to determine the ways in which it both contributed to and undermined attempts to foster Ukrainian political, literary, and cultural expansion. In the early years following the Ukrainian Revolution, first the Bolshevik party, and then the Soviet state recognized that it was imperative to gain support from the Ukrainian population. For a brief time a Ukrainian cultural and literary renaissance flourished, until the Soviet state ultimately proscribed all activity which did not occur under the aegis of the state. In the fifth chapter, I examine literary activity in Soviet Ukraine and the role of Mykola Khvylovy. By looking at the relationships among literary organizations and their connections to the Soviet State, I want to understand how Ukrainian literature was circumscribed by an increasingly repressive Soviet state. Lastly, I want to examine the literary life and works of Mykola Khvylovy in order to demonstrate his importance to this era, which has come to be known as “executed Ukrainian renaissance.” By analyzing Khvylovy’s polemical pamphlets and prose, I attempt to explain the author’s literary ideology and his vision for a new Ukrainian literature. In a close reading of Khvylovy’s Ia…Romantika, I consider aspects of the protagonist’s a psychological rupture, which reveals his self-doubt and uncertainty with the new revolutionary order.Russian, East European, and Eurasian Studie

Анализируется оценка мемуаристами значения крестьянской организации, ее взаимоотношения с политическими партиями, а также движение за создание Украинского крестьянского союза.The complex of memorial historical and revolution literature revealing All-Russian Peasant
Union (ARPU) regional structures activity is examined. The article purpose is to analyze basing
on the memorials of agrarians (participants of the movement) various aspects of regional locations
of Peasant Union social and political activity in Ukraine as well as a struggle for Ukrainian
Peasant Union creation. It is distinguished that the definition of the ARPU nature differed depending on the political background of memoirists - from accepting the Union as proper peasant organization disposed
to act in legal field (E.Chikalenko, D.Doroshenko) to formless structure without clear program,
how it was understood by a part of Russian social-democrats. Therefore came different degrees
of parties’ members participation in the operation of the Union. In Ukraine the most active role
in the creation and development of ARPU played the representatives of Ukrainian Liberal camp
together with the representatives of Socialist-Revolutionary party. In spite of being encouraged by parties’ activists, Peasant Union stayed fully independent organization guided by peasant interests. Memoirists who belonged to the former Union activists estimated it as a valid political power and an equal partner of other political organizations and, in case of Sumy ARPU committee, as a leading political party of the region.
The memorials recreate the picture of ARPU cells, which were mostly established from the
bottom upwards according to the chain reaction. In this regards, authors’ positive attitudes to massive
influxes of peasants to organization are stated. In memoirs conduction of peasant congresses, which
demonstrated the prevailing homogeneity of the peasants’ position on payless cession of landlords’,
imperial and church lands to peasants was noted as well as positive perception of revolution
democratic tasks - convention of information meetings, implementation of democratic freedoms,
release of political prisoners, etc. The attention to economic measures of local Union Committees
described by authors is emphasized. The role of peasant intelligence in the operation of Union units
is reviewed. Ukrainian political leaders’ activity aimed at Ukrainian Peasant Union (UPU) creation
is studied separately together with the roles of sertain political activists in this process.
It is concluded that the memoirs point at the list of important aspects of ARPU activity:
successful functioning of Peasant Union Units was due to a strong collaboration of intelligence
and peasant activists; substantial contribution in establishment and activity of ARPU commettees
was made by opposition political organizations, though their influence on peasantry and its
organization was not considerable; the creation of Peasant Union itself became possible due to
the peasantry politization and origin of public society
