Efficient near-room-temperature PPMgLN optical parametric oscillator pumped by an electro-optically Q-switched Tm:YAP laser

The transient conversion dynamics of a near-degenerate doubly-resonant optical parametric oscillator (DRO) based on periodically poled MgO:LiNbO 3 (PPMgLN) were investigated using a time-domain coupled-wave model. Operating in the mid-infrared (MIR) region, the DRO is primarily l...

Association between hippocampal ferroptosis-related changes and behavioral alterations in CCI rats with neuropathic pain

This study aimed to characterize behavioral alterations induced by chronic constriction injury (CCI) of the sciatic nerve and hippocampal ferroptosis in rats and to explore the association between hippocampal ferroptosis and behavioral changes accompanying neuropathic pain (NP)....

Competing Pasts in Bulgaria: The ‘Ethnic Crisis’ of 1989–1990 and Transitional Justice

Transitional justice in Bulgaria was incomplete and delayed due to the emergence around the June 1990 elections of two views on the communist past. One view sought justice for the crimes committed during early communism, whereas the other sought redress for the crimes committed d...

The history of research in workplace diversity: evolution, debates and future trajectories

Purpose This study aims to examine the historical evolution of the relationship between workplace diversity (WD) and firm performance within the domain of management research. Despite the original interpretation of WD in terms of social aspects, it is becoming increasingly integr...

Knowledge, perceptions and counselling practices regarding vasectomy among Portuguese physicians: a cross-sectional study

Purpose To assess knowledge, perceptions and counselling practices regarding vasectomy among Portuguese physicians from Obstetrics and Gynaecology (OB/GYN) and General and Family Medicine (GFM) specialties.Materials and methods A national cross-sectional observational study was c...

Finite-element-assisted interpretable graph attention learning for high-fidelity prediction of mass transport in fibrin biomaterials

Abstract Accurate prediction of spatial concentration fields within biomaterials is important for mass-transfer analysis and computational modeling of transport processes. This study develops an interpretable data-driven framework for spatially resolved mass-transport prediction...

Plenty of fish in the sea, but only one multimodal feather star robot

A feather star–inspired soft swimming robot achieves multimodal 3D maneuverability with minimal actuation using a mechanically intelligent body design.

Extraction-string ureteral stents and postoperative infection after flexible ureteroscopy: an IPTW-adjusted analysis

Extraction-string ureteral stents facilitate non-cystoscopic removal after ureteroscopy, but concerns remain regarding postoperative infection and accidental dislodgement. We evaluated whether extraction-string stents were associated with postoperative infection after flexible ur...

Outcomes of front-line tagraxofusp in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN) in a real-world scenario

Abstract Tagraxofusp (TAG), a CD123-directed protein-drug conjugate, is approved in front-line and relapsed/refractory blastic plasmacytoid dendritic cell neoplasm (BPDCN). Multicenter real-world outcomes and the contribution of up-front consolidation post-TAG remain less defined...

Using the Psychology Research Experience Preparedness (PREP) Program to Encourage Research Engagement Amongst Undergraduate Students

Background Undergraduate psychology research experiences offer many benefits for students. The Psychology Research Experience Preparedness (PREP) program was developed to demystify the research process and broaden participation amongst undergraduate psychology students. Objective...

Heart sound classification using machine learning approaches based on mel-frequency cepstrum coefficients (MFCCs) and statistical features

Heart sounds provide a valuable non-invasive source of information for the early detection of cardiac abnormalities. However, reliably distinguishing normal from abnormal heart sounds remains challenging in routine clinical practice because interpretation depends strongly on expe...

Experimental and machine learning analysis on Mn doped Fe2O3@Bi2S3 heterojunctions for visible light photocatalytic degradation of Rhodamine B

In this study, Mn-doped Fe 2 O 3 @Bi 2 S 3 nanocomposite heterojunctions were synthesized, characterized, and evaluated for their photocatalytic performance in the degradation of Rhodamine B (RhB) dye under visible light. A strong heterojunction structure was formed by combining...

Prevalence of malaria in the United Villages region, Northern Khartoum State, during armed conflict

Malaria remains a major public health concern in sub-Saharan Africa, where under-resourced health systems and environmental conditions continue to facilitate transmission. In Sudan, the situation has been further aggravated by the ongoing armed conflict that began in April 2023,...

How ventures maintain stakeholder support amidst operational legitimacy threats

Abstract Research Summary We explore how ventures mitigate operational legitimacy threats— threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition . Through an inductive study of four ventures w...

Local and global canopy height models reveal consistent large-tree forest conservation gaps despite low spatial agreement

Canada's coastal temperate rainforests are home to some of the world's largest trees. These forests support disproportionate carbon storage, high structural complexity, and habitat for a wide range of species. Historical logging focused on the most productive stands, combined wit...

Embedded Cardiorespiratory Monitoring Using a 77 GHz FMCW Radar: On-Chip Multi-Timescale Tiny 1D CNN and Whole-Node Power Evaluation

A 77-GHz radar can detect small chest movements induced by cardiac activity and respiration; however, typical systems transmit the acquired signals to an external computer for processing. This limits the development of autonomous and energy-efficient monitoring devices. This stud...

Mechanical Properties of Hybrid Natural Fiber–Carbon Fiber‐Reinforced Polypropylene Nonwoven Composites: Influence of Degree of Densification, Fiber Volume Fraction and Laminate Architecture

ABSTRACT Nonwoven composites based on flax fiber (NF)‐reinforced polypropylene (PP) offer a promising route toward sustainable lightweight structures but are limited by moderate mechanical performance. In this work, a hybridization concept employing carbon fiber (CF) nonwoven sur...

Divergent interfaces and convergent outcome in the structural basis of HIV-2 Vif antagonism of APOBEC3H

Abstract Primate lentiviruses counteract antiviral APOBEC3 (A3) cytidine deaminases through virion infectivity factor (Vif), which recruits A3 proteins to a Cullin–RING E3 ubiquitin ligase for proteasomal degradation. While HIV-1 Vif is well characterized, HIV-2 Vif remains poorl...

A non-biomineralized trilobitomorph euarthropod (Helmetiida) with appendicular morphology from the early Cambrian Chengjiang biota, China

Abstract Helmetiida is a major group of Trilobitomorpha and Artiopoda known from Cambrian Burgess Shale-type Lagerstätten. Phylogenetic studies have suggested that they are closely related to trilobites as their possible sister taxon. With seven genera and eight species, Helmetii...

Sociodemographic Heterogeneity in Gastronomic Tourism Spending and Willingness to Pay

This study examines whether sociodemographic characteristics are associated with three dimensions of gastronomic tourists’ economic behaviour: gastronomic spending propensity, premium willingness to pay (WTP) for gastronomic experiences, and premium WTP for local-value and sustai...
