Every developer hits a wall where simply writing functional code isn’t enough. You start optimizing the machine — the workflow — and that’s…

8 Python Libraries That Finally Turned My Chaos Into a System We’ve all been there: that moment when your Python project starts feeling less like elegant code and more like a tangle of duct tape …

Little tweaks, huge momentum.

Spreadsheets had a good run.

A novel series of magnetoelectric composites (1 − x)SrFe12O19–xLa0.5Nd0.5FeO3 (x = 0.00–1.00) was synthesized via a citrate-assisted sol–gel method to explore the interplay between structural evolution and multifunctional properties. X-ray diffraction and Raman spectroscopy revealed phase coexistence with crystalli

Perovskite solar cells (PSCs) have attracted significant attention due to their rapidly increasing power conversion efficiencies (PCEs), now exceeding 25.8%, along with low-cost fabrication and versatile material tunability. Among the core components of PSCs, hole transport materials (HTMs) play a pivotal role in e

IntroductionDiabetic foot ulcers (DFUs) are a significant cause of amputation and mortality in low‑ and middle‑income countries. However, Bangladeshi data on the bacterial spectrum and antimicrobial susceptibility patterns remain scarce.MethodsIn a cross‑sectional study at Chattogram Diabetic General Hospital, Bangladesh, 106 adults with DFUs provided deep tissue specimens as per grading for aerobic culture. Bacterial isolates were identified by standard methods and tested against 16 antibiotics according to Clinical and Laboratory Standards Institute (CLSI) disc diffusion guidelines. Clinical and sociodemographic data were summarised descriptively; resistance patterns were visualised using heat‑map clustering.ResultsCulture was positive in 81.1% (86/106) of participants. Across all participants, Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) were co‑dominant (each 26.4%, 28/106), followed by Klebsiella pneumoniae (K. pneumoniae) and Enterococcus species (spp.) (each 11.3%, 12/106), and Pseudomonas aeruginosa (P. aeruginosa) (9.4%, 10/106); polymicrobial infection was 3.8% (4/106). Resistance was widespread. In the Gram‑positive panel, erythromycin showed the highest resistance (S. aureus 92.9%; Enterococcus spp. 83.3%), with ampicillin/vancomycin/linezolid also high. In the Gram-negative panel, ampicillin, ciprofloxacin and cefuroxime carried heavy resistance burdens (reaching 100% in P. aeruginosa). By contrast, resistance to piperacillin-tazobactam and imipenem was low in E. coli (10.7% and 14.3%, respectively); in K. pneumoniae it was higher for piperacillin-tazobactam than imipenem (41.7% vs 16.7%); and in P. aeruginosa the pattern was reversed, with 10.0% resistant to piperacillin-tazobactam and 40.0% resistant to imipenem. Tigecycline retained 0% resistance across all taxa. Row‑wise clustering separated high‑ from lower‑resistance drug groups, making organism‑specific patterns immediately interpretable.ConclusionGram‑negative organisms were more frequent overall, and resistance to several commonly used β‑lactams and fluoroquinolones was high. Tigecycline showed the best preserved activity. Empirical treatment should be guided by local data, prioritise agents with retained activity against both Gram‑positive and Gram‑negative pathogens, and be promptly narrowed once susceptibilities are available. Continued local surveillance and strong antimicrobial stewardship are essential to limit further resistance.

Influenza and other respiratory viruses pose significant public health threats among SARI patients, yet comprehensive surveillance data remain limited in Pakistan. This prospective, multi-center study characterized the burden, distribution, and molecular evolution of respiratory viruses among hospitalized SARI patients across seven tertiary hospitals from November 2022 to June 2025. Specimens were tested using RT-PCR for influenza, SARS-CoV-2, and RSV, with 375 samples sequenced via Oxford Nanopore Technology. Among 11,451 specimens, 2818 (24.6%) tested positive: RSV (1648, 14.4%), influenza (855, 7.5%; 45% H1N1pdm09, 35% H3N2, 20% influenza B), and SARS-CoV-2 (315, 2.8%). RSV predominantly affected children under 2 years (63%), while influenza and SARS-CoV-2 primarily impacted adults aged 15–40 years. Male predominance (65–79%) reflected healthcare access barriers. Strong winter seasonality (December–February) was observed for influenza and RSV. ICU admission rates were 17% for influenza, 16% for RSV, and 4% for SARS-CoV-2. Shortness of breath was associated with influenza (OR = 1.62) and RSV (OR = 1.27), while malaise (OR = 2.24) and myalgia (OR = 3.87) was associated with SARS-CoV-2. Phylogenetic analysis revealed vaccine-matched influenza clades and rapid SARS-CoV-2 variant succession (3–4 months). RSV is the primary SARI pathogen in young children, necessitating maternal vaccines and nirsevimab implementation. Sustained genomic surveillance remains essential for pandemic preparedness.

The article traces how the Kumbh Mela is being reimagined from a myth-based bathing festival at four riverine sites into a civilisational template that links sacred time, water and geography across India. It argues that this expansion, which seeks to integrate diverse regions like Kerala and Kashmir into a unified Kumbh framework, risks erasing distinct ritual traditions and sacred cartographies, particularly Kashmir’s autonomous Shaivite-inflected religious landscape.
