In this paper, we study time delays experienced by photons propagating on charged shockwave backgrounds in five dimensions. In the absence of gravity — where the shockwaves are electric fields sourced by boosted charges — we derive positivity bounds for the four-derivative corrections to electromagnetism, reproducing previous results derived from scattering amplitudes. By considering the gravitational shockwaves sourced by Reissner-Nordström black holes, we derive new constraints in the presence of gravity. We observe the by-now familiar weakening of positivity bounds in the presence of gravity, but without the logarithmic divergences present in 4d. We find that the strongest bounds appear by examining the time delay near the horizon of the smallest possible black hole, and discuss on the validity of the EFT expansion in this region. We comment on our bounds in the context of the swampland program as well as their relation with the positivity bounds obtained from dispersion relations.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 9","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP09(2025)052.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Septal myectomy has been extensively demonstrated as an effective surgery for treating OHCM. However, it remains incompletely understood how the surgery would alter the mechanical and energetic states of the left ventricle (LV). In this study, microstructure-based finite element (FE) models were built for the LVs of two patients with OHCM to compute myocardial mechanics before and after septal myectomy. In addition, energy metrices spanning multiple scales were defined and calculated based on the results of FE analysis. The results showed that septal myectomy facilitated a significant improvement in the mechanical state of the LV, characterized mainly by the overall decreased while more homogeneously distributed myocardial tissue and cardiomyocyte stresses. Energetically, the total mechanical energies at the scales of the entire LV, myocardial tissue, and cardiomyocyte all decreased remarkably after septal myectomy. Moreover, the surgery induced a moderate increase in the efficiencies of mechanical energy conversion at the myocardial tissue and cardiomyocyte levels in the septal region. Although the mechanical and energetic parameters of the LV differed quantitatively between the two patients, they exhibited similar trends of change following septal myectomy. These results suggest that septal myectomy can improve the mechano-energetic state of the LV, and thereby may exert favorable influence on postoperative cardiac remodeling and adaptation. The proposed modeling method may offer a promising means for optimizing surgical planning or evaluating the therapeutic effects of septal myectomy for patients with OHCM.","PeriodicalId":489,"journal":{"name":"Biomechanics and Modeling in Mechanobiology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, liquid atmospheric pressure matrix-assisted laser desorption/ionisation (LAP-MALDI) mass spectrometry (MS) is applied to fast lipid and protein profiling of Candida albicans and Saccharomyces cerevisiae from cultured colonies. Species-specific lipid profiles were observed in the m/z 600-1100 range, dominated by phospholipids as confirmed by tandem mass spectrometry (MS/MS). Following simple solid phase extraction clean-up, LAP-MALDI mass spectra revealed multiply charged protein ions suitable for MS/MS analysis. For C. albicans, the fully mature, species-specific WHS11 protein (~ 7 kDa; P43074) was detected intact and confidently identified by top-down MS/MS proteoform sequencing, including the cleavage of the N-terminal methionine initiator and the associated N-terminal acetylation. For S. cerevisiae, a set of proteoforms were sequenced by MS/MS analysis, which led to the identification of two species-specific proteins within the 'UniProtKB reference proteomes + Swiss-Prot' target database. One of these was also detected intact, and sequenced and identified as the fully mature HSP12 protein (~ 11.5 kDa; P22943). This work demonstrates the potential of LAP-MALDI MS and MS/MS biotyping as a powerful, label-free platform for rapid fungal classification and proteoform characterisation, offering substantial improvements over conventional MALDI biotyping.","PeriodicalId":462,"journal":{"name":"Analytical and Bioanalytical Chemistry","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
