WinoNet:Reconfigurable look-up table-based Winograd accelerator for arbitrary precision convolutional neural network inference

To solve the hardware deployment problem caused by the vast demanding computational complexity of convolutional layers and limited hardware resources for the hardware network inference,a look-up table(LUT)-based convolution architecture built on a field-programmable gate array using integer multipliers and addition trees is used.With the help of the Winograd algorithm,the optimization of convolution and multiplication is realized to reduce the computational complexity.The LUT-based operator is further optimized to construct a processing unit(PE).Simultaneously optimized storage streams improve memory access efficiency and solve bandwidth constraints.The data toggle rate is reduced to optimize power consumption.The experimental results show that the use of the Winograd algorithm to build basic processing units can significantly reduce the number of multipliers and achieve hardware deployment acceleration,while the time-division multiplexing of processing units improves resource utilization.Under this experimental condition,compared with the traditional convolution method,the architecture optimizes computing resources by 2.25 times and improves the peak throughput by 19.3 times.The LUT-based Winograd accelerator can effectively solve the deployment problem caused by limited hardware resources.

An Exact Propagator for Solving the Triatomic Reactive Schrodinger Equation

The exact short time propagator, in a form similar to the Crank-Nicholson method but in the spirit of spectrally transformed Hamiltonian, was proposed to solve the triatomic reactive time-dependent schrodinger equation. This new propagator is exact and unconditionally convergent for calculating reactive scattering processes with large time step sizes. In order to improve the computational efficiency, the spectral difference method was applied. This resulted the Hamiltonian with elements confined in a narrow diagonal band. In contrast to our previous theoretical work, the discrete variable representation was applied and resulted in full Hamiltonian matrix. As examples, the collision energy-dependent probability of the triatomic H＋H2 and O＋O2 reaction are calculated. The numerical results demonstrate that this new propagator is numerically accurate and capable of propagating the wave packet with large time steps. However, the efficiency and accuracy of this new propagator strongly depend on the mathematical method for solving the involved linear equations and the choice of preconditioner.

The Phenomenological Approach as Epistemologically Support to Legitimize the Position of Oneself to the Other of Psychoanalysis

This work aims to show, in the phenomenology of Husserl, the relevance to seek the elements that give epistemological legitimacy and validity to the conceptualization that brings psychoanalytic theory to account for processes whose explanation necessarily imply to clarify that psychoanalysis, in contrast to psychological treatments, is not based on the effects of a relationship between the participants but in the positioning that each of them occupies relative to the other, particularly when having in mind the concept of transference and recognizing in it the position from which the analyst can give conditions of possibility--through his interventions--for which the patient may realize, analyze, and rethink his own position on what constitutes his discomfort. Husserl recaptures the Cartesian base from which opens philosophical reflection to a new area of research ＂in＂ consciousness where it is allowed to understand the relationship between subject and object from a new perspective that enables establishing an epistemology that substantiates the rigorous analysis of human subjectivity. Husserl＇s proposal introduces us to an epistemic field in which it can be shown and, that the psychoanalytic method which enables its effects is precisely the position of the analyst, while by his presence and intervention leads to the other in question, without having to abide by an alien desire, be able to position himself before his own desire. This analysis regarding the desire of oneself is indispensable to understand the elements at play in contemporary psychopathology, as in the present context the intensity of the demands generated in the economic apparatus, are experienced by the subject as arising from himself, erasing traces of his desire that is superseded by social imperatives that crushed and fragmented him.

Clinical Study on Extracorporeal Shock Wave Therapy plus Electroacupuncture for Myofascial Pain Syndrome

Objective: To observe the clinical effect of extracorporeal shock wave plus electroacupuncture(EA) on myofascial pain syndrome(MPS) and to investigate its treatment mechanism. Methods: Ninety cases who met the inclusion criteria were randomly allocated into an EA group, an extracorporeal shock wave therapy(ESWT) group and a combined therapy group, 30 in each group. EA was employed in the EA group, extracorporeal shock wave therapy in the ESWT group and EA plus extracorporeal shock wave therapy in the combined therapy group. The VAS, tenderness threshold and therapeutic efficacy were evaluated after three months of treatment. Results: After 2 weeks, 4 weeks and 3 months of treatment, the VAS scores in all three groups were significantly reduced and the tenderness threshold significantly elevated. The recovery rate and total effective rate were 23.3% and 83.3% respectively in the EA group, versus 40.0% and 90.0% in the ESWT group and 63.3% and 96.7% in the combined therapy group, showing statistical differences(P<0.05). Conclusion: EA combined with EWST works remarkably well for MPS.
