Human-Inspired Control of a Whip: Preparatory Movements Improve Hitting a Target.

Manipulating flexible and underactuated objects, such as a whip, remains a significant challenge in robotics. Remarkably, humans can skillfully manipulate such objects to achieve tasks, ranging from hitting distant targets to extinguishing a cigarette's in someone's mouth with the tip of a whip. This study explored this problem by constructing and modeling a 25-degree-of-freedom whip.

Size Effects in Climatic Aging of Epoxy Basalt Fiber Reinforcement Bar.

The purpose of this study was to obtain information on the influence of the size factor on the climatic aging of circular fiber plastics produced by pultrusion. The kinetics of moisture transfer was obtained in humidification and drying modes at 60 °C in samples of epoxy basalt fiber reinforcement bars: after 28 months of exposure in the extremely cold climate of Yakutsk and 30 months of exposure in the moderately warm climate of Gelendzhik. It was shown that the 2D Langmuir model adequately describes the kinetics.

Learning to manipulate a whip with simple primitive actions - A simulation study.

This simulation study investigated whether a 4-degrees-of-freedom (DOF) arm could strike a target with a 50-DOF whip using a motion profile similar to discrete human movements. The interactive dynamics of the multi-joint arm was modeled as a constant joint-space mechanical impedance, with values derived from experimental measurement. Targets at various locations could be hit with a single maximally smooth motion in joint-space coordinates.

Motor control beyond reach-how humans hit a target with a whip.

Humans are strikingly adept at manipulating complex objects, from tying shoelaces to cracking a bullwhip. These motor skills have highly nonlinear interactive dynamics that defy reduction into parts. Yet, despite advances in data recording and processing, experiments in motor neuroscience still prioritize experimental reduction over realistic complexity.

FPGA-Implemented Fractal Decoder with Forward Error Correction in Short-Reach Optical Interconnects.

Forward error correction (FEC) codes combined with high-order modulator formats, i.e., coded modulation (CM), are essential in optical communication networks to achieve highly efficient and reliable communication.

[The current methodological approaches in assessing nasal breathing function].

The techniques currently used in assessment of nasal respiration with classification and comparative analysis, own experience with maintenance of ATMOS-200 rhinomanometer are outlined. Nasal respiration is best to assess objectively with devices estimating aerodynamic resistance of the nose. The techniques of the anterior and posterior active rhinomanometry (rhinoresistometry) are effective.

[Antigenic and immunoglobulin preparations for the diagnosis of coxiellosis in the system of conjugated unidirectional serologic reactions].

The methods for obtaining antigenic and immunoglobulin preparations intended for the rapid serological diagnosis of coxiellosis were developed. The cells used as the basis for their preparation were formulated tanned sheep red blood cells. As sensitin, rabbit anti-C.

[The technology for manufacturing antiparasitic preparations. 3. The development of a technology for producing the anthelmintic embovin (pyrantel embonate) in finely dispersed form and the evaluation of its anthelmintic properties].

Manufacturing process for anthelmintic embovin in a micronized form have been developed. Embovin in the micronized form exhibited the highest activity.

[The structure and anthelmintic action of tricyclic analogs of praziquantel and 4-acylpiperazinones-2].

The toxicity and anthelminthic activity of the earlier synthetized tricyclic analogues of praziquantel and 4-acylpiperazinones-2 have been studied. Tricyclic compounds have shown the acute toxicity similar to that of praziquantel and neurotoxic effect typical of praziquantel. 4-acylpiperazinones-2 toxicity correlated with their anthelminthic effect.

[Ways and methods of searching for new anthelmintics].

The ways of searching for new anthelminthic agents among diverse chemical compounds are analysed. The most promising chemical groups are presented. It is recommended to test every drug using as many as possible experimental models.

[Experimental chemotherapy of alveolar hydatid disease. 12. The efficacy of drug forms of mebendazole and nocodazole with high bioavailability].

New formulations have been designed to increase the efficacy and bioavailability of the oral drugs mebendazole and nocodazole and were tested in CBA mice. A considerable increase in efficacy was established for a solid disperse formulation of certain composition with a relatively lower toxicity than in aqueous suspensions of the drugs.
