Commented on Macroporous nanowire nanoelectronic scaffolds for synthetic tissues
This investigation is following the known methodology, for example: "Extended studies will be needed to evaluate the nanoES for longer-term implants, although the main component of nanoES, SU-8, has demonstrated long-term chronic biocompatibility suitable for in vivo recording [34], [35]." and "we have demonstrated a 3D macroporous material/device platform that is distinct from either engineered tissue [6], [41] or flexible electronics [13], [?17], [42], and [?44]." But the improvements do not explained and "a conceptually new approach that meets this challenge by integrating nanoelectronics throughout biomaterials and synthetic tissues in three dimensions" was taken from my papers at https://issuu.com/r_sklyar/docs/harvmitfrontiers. Also there are an obvious disproportion between the images (or micrographs) and acquired results, for example Fig. 5: a-f and g-h. Moreover, they are substituted by the unjustified prognosis's, such as: "makes possible the detection of inflammation, ischaemia, tumour micro-environments or other forms of metabolic acidosis due to overproduction of organic acids or impaired renal acidification [39], [40]" and "can be exploited for a number of in vitro studies, including drug screening assays with these synthetic neural and cardiac tissues."

Commented on Outside Looking In: Nanotube Transistor Intracellular Sensors
The acquired data should added to Abstract. The main idea has been copied from my paper “A CNTFET-based nanowired induction two-way transducers", published in ISPN Nanotechnology at www.isrn.com/journals/nanotechnology/2012/102783, and the references within - issuu.com/r_sklyar/docs/-nwintracellsens12. Moreover, the technological advances Refs. 14, 18, 23, and 25 were implemented from other investigations. Also some cumbersome variant 'Refs. in Ref.' was introduced in the last ones, except [23].

Article

Commented on Imperceptible magnetoelectronics
The technological advancements in Figs. 2&4 on two full paged do not mentioned in Abstract. That is why some keywords would be useful. Fig. 1 is too huge and could be reduced, at least twice. The main idea was presented ten years before at CLAWAR 2004 Conference and finally published in the Positioning journal [www.scirp.org/journal/PaperInformation.aspx?paperID=5051#abstract] - issuu.com/r_sklyar/docs/imperceptible. Lack of the theoretical validation. Moreover, a single equation was placed in Discussion. The constructed "highly sensitive giant magnetoresistive (GMR) sensor elements" should be compared thoroughly with previously reported, and clearly presented in figures.

Commented on Localization of a Mobile Platform Equipped With a Rotating Magnetic Dipole Source
The main subject is 'localization', that is why the Index Term 'indoor navigation' is excessive. Also any term doesn't dedicated to the five-page theoretical portion. Moreover, analysis of "a structure of two coils placed orthogonally" is obvious which could be cited in a huge 'REFERENCES" section. For example, the paper "An Electromagnetic Localization and Orientation Method Based on Rotating Magnetic Dipole" (DOI 10.1109/TMAG.2012.2211375) by Sh. Song et al. "Navigation by fingerprinting, e.g., exploiting local magnetic anomalies" of Ref. [21] was originally invented in my paper 'Induction Magnetic Field Sensor as an Organ of Robot Vision' - publons.com/review/7531204, and some further one. The definition "ultralow frequency (ULF) band, i.e., 300–3000 Hz" is false. Figs. 5&6 are almost identical and they should be coincided. Also the linear graphs in Figs. 9&11 and noise figures Figs. 16&17 are low informative. Figs. 18&19 should be magnified, for example by showing data within X(4.95; 5.05) and Y (3.95; 4.05) only. Mention of the references in CONCLUSIONS is unacceptable and further equations should be substituted by the acquired data.

Commented on An Electromagnetic Localization and Orientation Method Based on Rotating Magnetic Dipole
The first Index Term is too general and two further ones are phrases with some combination of 'Index Term' itself! The description of Fig. 3 with the relevant equations are better suitable for Sect. II. More thorough comparing between simulation and experimental results should be placed in CONCLUSIONS. That is why two similar sentences in Abstract "Experimental results demonstrate a promising performance of this method." and CONCLUSIONS "Experimental results show that this method works well." do not enough. Also the difference of this orientation method with Ref. [4]&[7] should be explained. By the way, the authors of Ref. [4] are T. Nara, S. Suzuki, and Sh. Ando.

Article

Commented on Localization in 2D Using Beacons of Low Frequency Magnetic Field
The key point is a resonant mode of the beacon's coil that should be stressed in the title, or in Abstract, at least. By the way, its first part is obvious. Also any keyword doesn't dedicated to theoretical&simulation method which spreads on Sections II-VI (six pages of ten ones)! "Localization method based on a magnetic map" prior to Ref. [11] was invented in my paper 'Induction Magnetic Field Sensor as an Organ of Robot Vision' - publons.com/review/7531204, and some further one. Nothing was said about the excitation frequency deviations under temperature variations of the capacitances and the excitation current of supply batteries. More thorough comparing between simulation and experimental results would be useful in CONCLUSIONS.

Commented on A Reliability-Augmented Particle Filter for Magnetic Fingerprinting Based Indoor Localization on Smartphone
Index Terms "Magnetic" and "Smartphone" are obvious, instead more adequate are desirable. "Model to enhance the basic particle filter", "minimize errors in motion estimation and improve the robustness", and "reduce computation overhead" in Abstract (similarly in CONCLUSION) do not evidential. This needs a support by the acquired data. The mentioned smartphone magnetometers should be described in a view of its performance/instrumentation characteristics. Also the Wi-FI set of phones for Fig. 25 does not specified. Moreover, comparing this performance with the data of Ref. 4&24 could be useful. "Magnetic mapping method" in Ref. [43] was predefined by my paper 'Induction Magnetic Field Sensor as an Organ of Robot Vision' - publons.com/review/7531204. Also Ref. [45] is too general.

Article

Commented on ParkSense: Automatic Parking Positioning by Leveraging In-Vehicle Magnetic Field Variation
Index Terms should not be extended up to the phrases, such as "vehicular and wireless technologies". Figs. 3b, 4 b&c, and 5 (lower) should be shown in a logarithmic scale for better visibility. Also Fig. 11 could be magnified. "Magnetic based localization" Ref. [16] was previously presented in my paper 'Induction Magnetic Field Sensor as an Organ of Robot Vision' - publons.com/review/7531204. Also Refs. [1]-[8], [27], [28], and [34]-[36] do not valid now. The calculated and experimental results from Sects. IV&V should be summarized in Section VIII CONCLUSION.

Article

Commented on Magnetic Maps for Indoor Navigation
Index Terms could be more specific, for example, "Magnetic field measurements, magnetic fields, magnetometers" are almost the same. The performance data of "a mobile smartphone and its embedded sensors" do not explained. Figs. 10&12 are obvious. Also 3&15 are similar and they could be mutually substituted. "Developing magnetic maps" was done long before Ref. [2] in my paper 'Induction Magnetic Field Sensor as an Organ of Robot Vision' - publons.com/review/7531204. Also Refs, [17]&[18] do not cited in the text.

Commented on Position and movement sensing at metre standoff distances using ambient electric field
An estimate of position has been made by using of electric potential sensor, according to the known method for magnetic sensors - https://issuu.com/r_sklyar/docs/sklyarvsprance . Circuit diagram in Fig. 1 should be explained by some equations. Figure 3 could be composed with a single signal processing arrangement used, for better visibility.

Article

Commented on New perspectives on the dialogue between brains and machines
Some development of a bidirectional brain-machine interface has been performed by modeling mathematically. The main idea was copied from the already known works https://issuu.com/r_sklyar/docs/sklyarvsmussaivaldi. Lack of the digital results is substantially reducing clearness of the said perspectives.
