Abstract Informal judgments of sentence acceptability have long been the primary source evidence about grammaticality in syntax, and controversial just as long. In past decade, there has growing interest collecting analyzing according to formal protocols experimental psycholinguistics, an approach sometimes called syntax. This article reviews major issues relevant this approach, namely, relative reliability, validity, sensitivity, convenience vs. informal methods.
The Internet of Things (IoT) is widely predicted to comprise billions connected devices, many which will be wireless sensor nodes (WSN). Energy efficiency a huge challenge here, followed by node cost and ease software (SW) development. Addressing all the above, this paper presents an 11.7 pJ/cycle subthreshold ARM Cortex-M0+ WSN processing subsystem implemented in low-leakage 65 nm CMOS. Voltage frequency scalability from 850 nW active power at 250 mV 66 MHz above 900 mV, with fully...
The Internet of Things is widely expected to comprise billions connected devices, many which will be wireless sensor nodes (WSN). One challenge this poses energy efficiency, as it prove cost-prohibitive regularly replace batteries. Node cost another concern, demand ever-greater integration. Ease SW development must also remain a priority HW designers. Addressing all the above, paper presents an 11.7pJ/cycle subthreshold WSN processing sub-system implemented in low-leakage 65nm CMOS, scalable...
Flip-flops are essential building blocks of sequential digital circuits, but typically occupy a substantial proportion chip area and consume significant amounts power.This work proposes 18TSPC, new topology fully-static contention-free Single-Phase Clocked (SPC) Flip-Flop (FF) with only 18 transistors, the lowest number reported for this type.Implemented in 65nm CMOS, it achieves 20% cell reduction compared to conventional Transmission Gate FF (TGFF).Simulation results show proposed 18TSPC...
We live in an interconnected world. Computing power once reserved for server rooms now resides our pockets. Tablets outsell PCs. As marked as these changes have been, we are entering a new era of vastly greater connectivity, where people interact with the world around them entirely ways. The Internet Things is its infancy, so predictions precisely what it will become dangerous, but several things clear. First, leaf nodes network share some device and technology properties terms cost...
Abstract Through a consideration of the noun inflections Finnish, we examine Butterworth’s (1983) full-listing hypothesis (FLH), that whole-word forms are stored in mental lexicons language learners/users. While previous studies have consistently confirmed complex derivational constructions stored/retrieved this way current consensus is inflectional not, primarily because extremely large number Finnish grammar projects. We challenge reasoning favor new theory posits dual lexicon for...
ABSTRACT Infants' sensitivity to word units in fluent speech was examined by inserting 1 sec pauses either at boundaries between successive words (Coincident versions) or syllables within (Noncoincident versions). In Experiment 1, 24 11-month-olds listened significantly longer the Coincident versions. 2, four-and-a-half-and nine-month-olds did not exhibit preference for versions that showed. When stimuli were low-pass filtered 3, showed no versions, suggesting they rely on more than prosodic...
RC Relaxation Oscillators (RxO) are attractive for integrated clock sources compared to LC and ring oscillators (RO), as pose integration challenges RO designs have limited voltage temperature (V-T) stability. RxOs generate a whose time period (T <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">P</inf> ) depends only on the timing resistor (R) capacitor (C). Ideally, T is independent of V-T; however, most use reference (V...
IoT requirements are almost as varied the Things to which they applied, but common demands maximum battery life with minimum system cost and physical volume. Sub-threshold operation is promising, even a single un-optimized or always-on component can eliminate low-voltage gains elsewhere. This work presents highly integrated sub-threshold capable ARM based MCU fully multi-mode IVR, power control, on-chip clock sources, achieving 12.44pJ/cycle active energy (6.3pJ/cycle ideal), 139.4nW standby...

Realizing the vision of a trillion IoT sensor nodes demands ultra low-power (ULP) compute, typically implemented using synchronous digital systems. These require clock sources which must be fully integrated to meet low system-cost requirements. Hence, relaxation oscillators (RxOs) are popular. Their need for precision references and high-speed comparators can challenge power budgets; hence, prior works have explored low-speed closed-loop control RxOs alleviate this issue. This paper adopts...
Recent research has shown subthreshold operation to reduce active energy in low-power MCUs [1], [2], [5]. However, some applications impose additional constraints. For battery-powered sensor nodes deployed remote locations, the MCU may lie dormant for long periods, only waking up when a detects activity. such cases, needs very low sleep power maximize battery lifetime, deterministic real-time response capture rare events, and energy-efficient with enough compute memory run useful workloads....

The goal of this paper is to discuss phonetic evidence relating the production tone sandhi in Mandarin. Two views are contrasted: standard ”categorical” view, whereby 3 treated similarly a/an allomorphy English, and an alternative ”gradient” which treats as similar flapping English. Evidence presented for two main claims. First, based on a review literature, it appears that native speakers Beijing Mandarin process more line with gradient while other varieties (including Taiwan Mandarin)...
This paper presents a technique, called subclock power gating, for reducing leakage during the active mode in low performance, energy-constrained applications. The proposed technique achieves reduction through two mechanisms: 1) gating combinational logic within clock period (subclock) and 2) virtual supply to less than Vth rather shutting down completely as is case conventional gating. To achieve this reduced voltage, pair of nMOS pMOS transistors are used at head foot gated symmetric rail...
