Progress depends on unbalance and disorder [PDF]
1997 International Symposium on Technology and Society Technology and Society at a Time of Sweeping Change. Proceedings, 2002 Walking is a state of unbalanced body-not to fall down, it takes away. Technology is another state of progress depending on unbalanced structures of human functions and relations. In balanced societies and cultures which are considered as technologically primitive, what we see is a lack of technology, but also a state of balance and order.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Functional assessment of patients with vertigo and dizziness in occupational medicine
Medycyna Pracy, 2018 Background Balance assessment relies on symptoms, clinical examination and functional assessment and their verification in objective tests. Our study was aimed at calculating the assessment compatibility between questionnaires, functional scales and ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Fault diagnosis method for rotor system of centrifugal compressor units
You-qi chuyun, 2023 The rotor system of the centrifugal compressor unit comprises the rotor and the support structure. The change in the rotor balance state and the abnormal stiffness of the composite spring are common faults of the rotor system.

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Active Currents, Power Factor, and Apparent Power for Practical Power Delivery Systems
IEEE Access, 2020 Concepts of apparent power and power factor as measures of a system's power delivery capability are over a century old but have not been defined in one general, rigorous and acceptable way.
