Theories and Practices of Chinese Community Correction System

The emergence and development of community correction system adapts to the international trend of punishment from severity to tenderness, reflecting the concepts changed from “punitive retribution” to “correction and rehabilitation”. Taking into account the fundamental purpose of community correction system, we should establish a scientific evaluation system focusing on the effects of correction process upon the offenders returning to society. Currently there is a certain bias against the evaluation criteria of community correction system

The auditory stimulus facilitates memory guidance in distractor suppression in males with substance use disorder

IntroductionRepresentations in working memory can affect distractor suppression in human visual search, and this process is modulated by a separate top-down cognitive control. An increasing body of research has demonstrated that patients with substance use disorder (SUD) have deficits in cognitive control over filtering interference by perceptual distractors. However, their ability to resist proactive interference from working memory has received comparatively less attention.MethodsHere, we investigate this issue by employing a working memory/visual search dual-task paradigm. An intervening gap-location search task was instructed to be performed while participants memorized a written color word, with congruent auditory information present during the memory encoding phase on half of the trials.ResultsResults showed that there was a reliable response time (RT) advantage when the meaning of the memory sample agreed with the color of one of the distractors under the visual alone condition. However, such a result was only found in the control group. More importantly, both groups exhibited comparable facilitation under the audiovisual condition, with the facilitation effect appearing later in the SUD group. Furthermore, the facilitation effect was superior in magnitude and time course under the audiovisual condition to the visual alone condition.DiscussionThese findings highlight how patients with SUD resist distractor interference at the memory level and extend our understanding of how working memory, selective attention, and audiovisual enhancement interact to optimize perceptual decisions in patients with SUD

Synthèse et caractérisation de nouvellespolycétones aliphatiques à partir des cétènes

L objectif de cette étude est de synthétiser de nouvelles architectures de polycétones aliphatiques à base de cétènes, possédant une température de fusion plus basse que le polydiméthylcétène, tout en conservant une température de dégradation élevée, afin d élargir sa fenêtre de mise en œuvre.La synthèse du diméthylcétène et / ou de l éthylcétène a été réalisée par pyrolyse de l anhydride isobutyrique et/ou butyrique à 625C sous 40 mbar. Un copolymère statistique a été d abord synthétisé par copolymérisation entre le diméthylcétène et l éthylcétène, par voie cationique à -78C ; ensuite en utilisant un amorceur de Friedel-Craft, un polydiméthylcétène possédant une architecture étoilée a été obtenu. Ces deux polymères ont permis d atteindre l objectif initialement fixé : ils présentent un endotherme de fusion à environ 180C, une bonne stabilité thermique similaire à celle du polydiméthylcétène (Tdégradation = 300C), et en particulier, de très bonnes propriétés barrières à l oxygène en milieu humide (jusqu à 95% HR).The objective of this study is to synthesize new architectures of ketene-based aliphaticpolyketones, having a lower melting temperature than polydimethylketene, while maintaining a high degradation temperature, in order to widen the processing window. The synthesis of dimethylketene and / or ethylketene was succeeded by the pyrolysis of isobutyric and / or butyric anhydride at 625C under 40 mbar. A random copolymer was first synthesized by the cationic copolymerization between dimethylketene and ethylketene, at -78 C; then using a Friedel-Craft initiator, a star-shaped polydimethylketene was obtained. These two polymers have reached the initial goal of this study: they possess a melting endotherm at about 180C, a good thermal stability similar to polydimethylketene (Tdegradation = 300C), and in particular, excellent oxygen barrier properties in wet atmosphere (up to 95% RH).ROUEN-INSA Madrillet (765752301) / SudocSudocFranceF

L-SRR: Local Differential Privacy for Location-Based Services with Staircase Randomized Response

Location-based services (LBS) have been significantly developed and widely deployed in mobile devices. It is also well-known that LBS applications may result in severe privacy concerns by collecting sensitive locations. A strong privacy model ''local differential privacy'' (LDP) has been recently deployed in many different applications (e.g., Google RAPPOR, iOS, and Microsoft Telemetry) but not effective for LBS applications due to the low utility of existing LDP mechanisms. To address such deficiency, we propose the first LDP framework for a variety of location-based services (namely ''L-SRR''), which privately collects and analyzes user locations with high utility. Specifically, we design a novel randomization mechanism ''Staircase Randomized Response'' (SRR) and extend the empirical estimation to significantly boost the utility for SRR in different LBS applications (e.g., traffic density estimation, and k-nearest neighbors). We have conducted extensive experiments on four real LBS datasets by benchmarking with other LDP schemes in practical applications. The experimental results demonstrate that L-SRR significantly outperforms them.Comment: accepted to CCS'22; full versio

Invited - Droplets driving and sensing pixel circuits for thin film transistor-based digital microfluidics

Thin film transistor-based active-matrix digital microfluidics (AM-DMF) is an emerging and promising technology for large-scale parallel biological sample handling. With electrowetting-on-dielectric (EWOD) method, DMF chip can realize accurately controlling discrete droplets, thus it has great application prospects in biology, chemistry, and drug discovery. With the rapid development of micro-analysis and detection requirements, the precise control of droplets in DMF chips is increasingly required, so it is necessary to conduct the real-time sensing of droplet position. Figure 1 shows the designed droplet position detection unit circuit. The circuit consists of six thin film transistors, T1-T6. The input signals mainly include the enable signal Ven, the reverse enable signal Venb, the discharge signal Vdischarge, the detection signal Vdetect, and the ground signal Vgnd. The signal Vdrive is the driving voltage applied for driving electrode. Cpixel is the equivalent capacitance between the two plates of a pixel electrode in a microfluidic chip. Vout is the output voltage signal. Please click Download on the upper right corner to see the full abstract

Graphene ballistic nano-rectifier with very high responsivity

Although graphene has the longest mean free path of carriers of any known electronic material, very few novel devices have been reported to harness this extraordinary property. Here we demonstrate a ballistic nano-rectifier fabricated by creating an asymmetric cross-junction in single-layer graphene sandwiched between boron nitride flakes. A mobility ∼200,000 cm(2) V(−1) s(−1) is achieved at room temperature, well beyond that required for ballistic transport. This enables a voltage responsivity as high as 23,000 mV mW(−1) with a low-frequency input signal. Taking advantage of the output channels being orthogonal to the input terminals, the noise is found to be not strongly influenced by the input. Hence, the corresponding noise-equivalent power is as low as 0.64 pW Hz(−1/2). Such performance is even comparable to superconducting bolometers, which however need to operate at cryogenic temperatures. Furthermore, output oscillations are observed at low temperatures, the period of which agrees with the lateral size quantization
