IEEE AccessTask-oriented dialog policy learning is often formulated as a Reinforcement Learning problem whose rewards from the environment are extremely sparse, which means that the agent will often not find the reward by acting randomly.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Quantitative Methods in Economics, 2015 Consider a finite population of N units. Let (0,1) denotes the fraction of units with a given property. The problem is in interval estimation of on the basis of a sample drawn due to the simple random sampling without replacement.

Sampling without Replacement Leads to Faster Rates in Finite-Sum Minimax Optimization
, 2022 We analyze the convergence rates of stochastic gradient algorithms for smooth finite-sum minimax optimization and show that, for many such algorithms, sampling the data points without replacement leads to faster convergence compared to sampling with ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Enhanced estimation of population mean via exponential-type estimator using dual auxiliary inputs
Applied Mathematics in Science and EngineeringWithout having to interview every person, we may draw conclusions about the whole population by estimating the population mean, a fundamental summary statistic that is obtained from a sample.

An elimination procedure for unequal probability sampling without replacement
, 1996 An exact without replacement sampling procedure with fixed sample size and unequal inclusion probabilities is presented. The proposed method eliminates a unit of the population at each of the N-n steps of the algorithm in order finally to retain n units.

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.
