An attempt has been made to find some valuable information for particle detection with the help of Solid State Nuclear Track Detectors. The detector is characterized by a critical value of the energy-loss rate by the charged particle. Only those charged particles which give up energy exceeding the critical value alone can produce teachable tracks. The detection thresholds of nuclear track detectors can be specified in terms of their energy loss rates. The findings have been found within a good (...) agreement with the other works. (shrink)

Artificial Immune Systems (AIS) are intelligent algorithms derived on the principles inspired by human immune system. In this research work, electroencephalography (EEG) signals for four distinct motor movement of human limbs are detected and classified using Negative Selection Classification Algorithm (NSCA). For this study, a widely studied open source EEG signal database (BCI IV - Graz dataset 2a, comprising 9 subjects) has been used. Mel Frequency Cepstral Coefficients (MFCCs) are extracted as selected feature from recorded EEG signals. Dimensionality reduction of (...) data is carried out by applying two hidden layered stacked auto-encoder. Genetic Algorithm (GA) optimized detectors (Artificial Lymphocytes) are trained using Negative Selection Algorithm (NSA) for detection and classification of four motor movements. The trained detectors consist of four sets of detectors, each set is trained for detection and classification of one of the four movements from the other three movements. The optimized radius of detector is small enough not to mis-detect the sample. Euclidean distance of each detector with every training dataset sample is taken and compared with optimized radius of detector as a non-self detector. Our proposed approach achieved a mean classification accuracy of 86.39% for limb movements over 9 subjects with a maximum individual subject classification accuracy of 97.5 % for subject number eight.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Socrates Dissatisfied: An Analysis of Plato’s Crito by Roslyn WeissMark L. McPherranRoslyn Weiss. Socrates Dissatisfied: An Analysis of Plato’s Crito. New York: Oxford University Press, 1997. Pp. xii + 187. Cloth, $39.95.The speech by ‘the Laws’ of the Crito has commonly been understood as a case of Socratic ventriloquism, voicing a doctrine of authoritarian civic obligation that Socrates himself endorses. This, of course, generates the standard problem of (...) reconciling this docile son of Athens with the radically autonomous Socrates of the Apology, a man obedient only to the dictates of his own reason. Roslyn Weiss’s book sets out to challenge this mainstream reading.On Weiss’s account, the speech of the Laws is a piece of crafty Socratic rhetoric antithetical to Socrates’ own convictions. Its purpose, then, is to convince not the reader but the lawless and unphilosophical Crito that Socrates ought to remain in Athens, using terms that Crito can comprehend (terms that will benefit his soul by making him more law-abiding). Despite this false ‘oratory’ (50b6–8), however, Socrates’ own first allegiance is to “justice and philosophy” (3) whose principles dictate that he suffer the court’s judgment, “abiding by the things agreed to” at his trial (Cr. 50a2–3).Although others have argued for this thesis, this is the first book-length argument of its kind and it supersedes all previous attempts in its persuasiveness and its thorough and detailed treatment: sensitive not only to the dialogue’s Greek and argumentative structure, but also to its literary/characterological nuances, it establishes an important scholarly outpost on the interpretation of the Crito and a worthy challenge to Richard Kraut’s reading. It is, finally, written in a remarkably engaging, clean and effective style, addressing the secondary scholarship adequately, and providing a useful bibliography and general index (though, regrettably, no Index Locorum).The book essentially follows the text of the Crito in a series of nine chapters. After a short Introduction, Chapter 2 begins by portraying Socrates as an autonomous moral agent utterly devoted to justice; Chapter 3 distinguishes Crito from Socrates; Chapter 4 contends that 46b–50a outlines Socrates’ complete argument against escape (one compatible with the principles of the Apology); Chapter 5 unpacks Socrates’ hint at 50a–d that the Laws will be offering only rhetorical arguments; Chapter 6 outlines these arguments and their logical flaws; Chapter 7 addresses Socrates’ characterization of their effect as ‘Corybantic’ (54d); Chapter 8 explains how the Laws are able to “boost Crito to a higher rung on the moral ladder,” (6); and finally, Chapter 9 reaffirms the radical moral independence of Socrates.Provocative and impressive, the book is bound to provoke criticism and reservations in its readers. Here I can only record a sample of my own. First, it seems to me that Weiss’s desire to portray Socrates as a slave of reason and not the state leads her astray when she tries to account for Socrates’ apparent reliance on the extrarational (15–23). Weiss, for example, tries to map out a new third alternative to the opposition between Vlastos’ view that the daimonion is no more than a kind of subjective, contentless hunch and the Brickhouse, Smith and McPherran view that the daimonion can oppose and ‘trump’ the results of rational deliberation. As she sees it, for Socrates the daimonion is not a voice independent of, and in potential conflict with, his own thinking; rather, it is the voice of his own unconscious beliefs, restraining him for his own reasons from [End Page 620] doing what he is tempted to do in moments of weakness. There is much to be said against this account, but it will suffice to point out that whatever the true nature of the daimonion might have been, Socrates is not likely to have been sympathetic to Weiss’s analysis of it. All our evidence, after all, indicates that Socrates takes the cause of the daimonion to be a god or daimoôn in the traditional sense of those terms (see, e.g., Ap. 27b–28a). Weiss’s proposal also runs up against texts such as Lysis 218C4–8 and 215C4–5, where Socrates recounts an... (shrink)

This paper discusses the introduction of fraudulent “molecular detector” technology into Mexico. The case is used to argue that contemporary science and technology studies’ approaches to scientific policy-making make basic assumptions about the societies they operate in that are inconsistent with the Mexican context. This paper also argues that contrary to what happens in the so-called Global North, the relative power of Mexican science in government and policy circles is as much limited by its relatively weak position as much (...) as it is by self-censorship and unrealized impact in the country’s fragile democracy. The case is also used to highlight the necessity for more politically involved scientific institutions in Mexico, as these become critical safeguards against incoming destabilizing technologies from more powerful nations into the local “peripheral” context.

We consider the questions of whether or not large language models (LLMs) have beliefs, and, if they do, how we might measure them. First, we consider whether or not we should expect LLMs to have something like beliefs in the first place. We consider some recent arguments aiming to show that LLMs cannot have beliefs. We show that these arguments are misguided. We provide a more productive framing of questions surrounding the status of beliefs in LLMs, and highlight the empirical (...) nature of the problem. With this lesson in hand, we evaluate two existing approaches for measuring the beliefs of LLMs, one due to Azaria and Mitchell (The internal state of an llm knows when its lying, 2023) and the other to Burns et al. (Discovering latent knowledge in language models without supervision, 2022). Moving from the armchair to the desk chair, we provide empirical results that show that these methods fail to generalize in very basic ways. We then argue that, even if LLMs have beliefs, these methods are unlikely to be successful for conceptual reasons. Thus, there is still no lie-detector for LLMs. We conclude by suggesting some concrete paths for future work. (shrink)

The influence of light on the lives of living organisms is all-pervasive, affecting movement, vision, behavior, and physiological activity. This book is a biophysically grounded comparative survey of how animals detect light and perceive their surroundings. Included are discussions of photoreceptors, light emitters, and eyes. The book focuses in particular on the kinds of optical systems that have evolved, beginning with unicellular organisms that detect and respond to light through to more advanced and complex designs for imaging. The relevance of (...) these studies extends beyond biology, since these findings can be used to help develop photoreceptor energy conversion and information systems, and optical imaging devices with a wide range of everyday applications. The book will appeal to biophysicists, photobiologists, bioengineers, neuroscientists, and all researchers working in the area of vision and visual optics. (shrink)

Terms of service of on-line platforms too often contain clauses that are potentially unfair to the consumer. We present an experimental study where machine learning is employed to automatically detect such potentially unfair clauses. Results show that the proposed system could provide a valuable tool for lawyers and consumers alike.
