In this study, we propose a force sensor using a shape-memory polymer (SMP) whose stiffness varies according to the temperature. An SMP can be deformed above its glass transition temperature (Tg) by applying a small load. A deformed SMP maintains its shape when cooled below Tg and returns to its predefined shape when subsequently heated above Tg. The reversible change in the elastic modulus bet...

Measurements of microbial extracellular polymeric substances (EPS) of natural field populations are required to understand the processes of biogenic stabilization and the microbial ecology of intertidal sediments. EPS in sediments can be measured by the phenol-sulfuric acid assay to measure carbohydrate concentration in sediment samples. We conducted comparative studies of storage and extractio...

In this study, the effects of the addition of Tween 80 and acetone on secretion, structure and antioxidant activities of Lentinus tigrinus exopolysaccharides (EPS) were investigated. It was found that Tween 80 and acetone displayed a stimulatory effect on EPS secretion. The EPS obtained by the addition of Tween 80 (EPS-T), acetone (EPS-A) and control (EPS--C) were purified by Sepharose CL-6B ge...

Machine learning (ML) problems commonly applied to big data by existing distributed systems share and update all ML model parameters at each machine using a partition of data — a strategy known as data-parallel. An alternative and complimentary strategy, model-parallel, partitions model parameters for non-shared parallel access and update, periodically repartitioning to facilitate communication...

We consider single-server queues with exponentially distributed service times, in which the arrival process is governed by a semi-Markov process (SMP). Two service disciplines, processor sharing (PS) and random service (RS), are investigated. We note that the sojourn time distribution of a type-l customer who, upon his arrival, meets k customers already present in the SMP/M/1/PS queue is identi...

We modified the charge equilibration method (QEq) of Rappe et al. by including the third and fourth order terms in the series expansion for the energy of charged atoms. This leads to a self-consistent scheme for obtaining charges and total energy in a molecule. We combined the modified QEq with a scaled morse potential (SMP) to get a new potential, SMP/QEq. The SMP/QEq method allows to do reali...

Magnetic relaxation measurements on a series of Y1−xPrxBa2Cu3O7− x=0.13, 0.34, and 0.47 single crystals were performed over a large field and temperature range in order to investigate the characteristics of the vortex matter across the second magnetization peak SMP . The magnitude of the SMP varies nonmonotonically with Pr concentration, i.e., the irreversible magnetization normalized by its va...

The creep and recovery of 5% carboxyl-terminated butadiene acrylonitrile (CTBN) modified epoxy shape memory polymers (SMP) was studied. The results were compared with those for the unmodified epoxy SMP. The glass transition temperatures (Tg) were determined using Advanced Rheometric Expansion System (ARES). The creep behavior of the unmodified epoxy and 5wt.% CTBN modified epoxy SMP were studie...

PURPOSE Fluoroquinolones, rapidly gaining prominence in treatment of Stenotrophomonas maltophilia (SMP), are noted for their potency and tolerability. However, SMP may rapidly acquire resistance to fluoroquinolones. We evaluated associations of clinical factors with acquisition of levofloxacin resistance (LFr) in SMP. MATERIALS AND METHODS Our retrospective cohort study was based on patient d...
