Polymorphic mimicry - When Herpes Isn’t Just Herpes: Genital Herpes Mimicking Secondary Syphilis: A Case Report

Abstract Background: Herpes simplex virus (HSV) infections can present atypically, mimicking a variety of other dermatologic and sexually transmitted diseases. This clinical variability can lead to misdiagnosis and delayed treatment. Case Presentation: We present the case of a 47...

Na/K-ATPase Signaling in Adipocytes Promotes Atherosclerosis

BACKGROUND: Adipocyte dysfunction is closely associated with oxidative stress and chronic inflammation, which contribute to systemic metabolic disturbances and atherosclerosis. We previously identified the NKA (Na/K-ATPase) α1 subunit as a signal transducer that activates Src-fam...

Droughts and borrowing patterns in poor countries: Evidence from Tanzania

This paper examines whether and to what extent droughts reshape household borrowing patterns in fragmented credit markets in developing economies. Using nationally representative household panel data from the two most recent waves (2014/15 and 2020/21) in Tanzania combined with d...

Rapid landslide mapping during the 2023 Emilia-Romagna disaster: assessing automated approaches with limited training data

Abstract. The catastrophic rainfall events of May 2023 in the Emilia-Romagna region, Italy, triggered more than 80 000 landslides, as documented in a publicly available inventory (https://doi.org/10.5281/zenodo.13742643, Pizziolo et al., 2024), and placed extraordinary demands on...

Health psychology in the age of social media: pointers for future research

Social media has become ubiquitous in daily life, transforming how we interact, exchange information, and form relationships. It is therefore not surprising that social media research has spurred, with scholars investigating a diverse range of topics. However, it has also become...

Biliary Atresia With Situs Inversus Abdominalis Managed by Kasai Portoenterostomy: A Case Report From Muhimbili National Hospital, Tanzania

ABSTRACT Biliary atresia associated with situs inversus abdominalis is a rare congenital combination that complicates diagnosis and surgical orientation. Early recognition, meticulous preoperative planning, and timely Kasai portoenterostomy can achieve favorable short‐term outcom...

Cheminformatic identification of small molecules targeting acute myeloid leukemia

Abstract Acute myeloid leukemia (AML) is an aggressive hematological malignancy with poor prognosis and high relapse rates when treated with cytotoxic chemotherapeutics. Previously, we identified a family of small molecules that modulate mitochondrial function, referred to as PS1...

Selective Similarity Preference: People with a “Darker Core” Desire More Partner Similarity in Dark Traits but Not in Big Five

Research on assortative mating has shown that couples share strong similarities in demographic and attitudinal variables, while the similarity in personality is generally weak. However, a recent meta-analysis indicated that couple similarity in dark traits is considerably greater...

Experimental Study on Smart Sloped Rolling-type Bearings Integrated with Early Prediction of Peak Velocity

The use of sloped rolling-type bearings (SRBs) to protect critical equipment from seismic damage has been widely adopted. However, maintaining SRB displacement responses within safe limits often requires a large damping force, which results in unacceptable accelerations. This hig...

Optimal Energy Use Strategy of Load Aggregators with Heterogeneous Energy Storage in a Community Integrated Energy System Based on Hybrid Game Theory: Considering Participant Contribution

Abstract With the advancement of energy storage technology, the user side equipped with heterogeneous storage has become the norm. Under this context, how to further improve energy utilization efficiency and reduce energy cost via heterogeneous energy sharing among diverse users...

A Hybrid Knowledge-Enhanced Legal AI System for Construction Contract Disputes

Abstract With rapid urbanization and expanding infrastructure, construction contract disputes are increasing in volume and complexity, challenging traditional adjudication. This study proposes a domain-specific legal artificial intelligence (AI) system for construction contract d...

Orientation-Reversing Crystallographic Rigidity

Abstract This paper provides a combinatorial characterisation for generic forced symmetric rigidity of bar-joint frameworks in the Euclidean plane that are symmetric with respect to the orientation-reversing wallpaper group $$\mathbb {Z}^2\rtimes \mathcal {C}_s$$ Z 2 ⋊ C s , also...

A determinant on birational maps of Severi–Brauer surfaces

We define a determinant on the group of automorphisms of non-trivial Severi–Brauer surfaces over a perfect field. Using the generators and relations, we extend this determinant to birational maps between Severi–Brauer surfaces. By means of this determinant and a group homomorphis...

Simultaneous Computation with Multiple Prioritizations in Multi-Agent Motion Planning

Multi-agent path finding (MAPF) in large networks is computationally challenging. An approach for MAPF is prioritized planning (PP), in which agents plan sequentially according to their priority. Albeit a computationally efficient approach for MAPF, the solution quality strongly...

Nanofiber-based second-order atomic Bragg lattice for collectively enhanced coupling

Abstract We propose two experimental schemes for nanofiber-based compensated optical dipole traps that optimize the collective coupling of a one-dimensional array of atoms. The created array satisfies the second-order Bragg condition (d = λ), facilitating constructive interferenc...

Mitigating algorithmic bias in the UK civil service: Challenges and implications for practice

This article examines algorithmic bias mitigation in the context of the UK's civil service, specifically the Department of Work and Pensions (DWP). Despite various algorithmic bias mitigation approaches being suggested in the literature, little research has examined how these mig...

Dynamic asymptotic dimension growth for group actions and groupoids

We introduce the notion of dynamic asymptotic dimension growth for actions of discrete groups on compact spaces, and more generally for locally compact étale groupoids. Moreover, we demonstrate that the asymptotic dimension growth for a discrete metric space of bounded geometry i...

Dirichlet Forms of Diffusion Processes on the Thoma Simplex

Abstract We study a prominent two-parameter family of diffusion processes $$X_{z,z'}$$ X z , z ′ on the infinite-dimensional Thoma simplex. This family was constructed by Borodin and Olshanski in 2007 and it closely resembles both the Ethier–Kurtz infinitely-many-neutral-alleles...

A General Latent Embedding Approach for Modeling Non-uniform High-dimensional Sparse Hypergraphs with Multiplicity

Recent research has shown growing interest in modeling hypergraphs, which capture polyadic interactions among entities beyond traditional dyadic relations. However, most existing methodologies for hypergraphs face significant limitations, including their heavy reliance on uniform...

Maximal subgroups in torsion branch groups

We study the maximal subgroups of branch groups and obtain a criterion that ensures that certain spinal groups are contained in the class \mathcal{MF} of groups with all maximal subgroups of finite index. This allows us to construct branch groups within \mathcal{MF} exhibiting no...
