Anomalous Hall effect (AHE) is a fundamental spin-dependent transport property that widely used in spintronics. It generally expected currents carrying net spin polarization are required to drive the AHE. Here we demonstrate that, contrast this common expectation, spin-neutral tunneling AHE (TAHE), i.e. TAHE driven by currents, can be realized an antiferromagnetic (AFM) tunnel junction where AF...

numerous causes are reported for ulnar nerve compression at the wrist, known as guyon's tunnel syndrome. in the present article, a patient with guyon's tunnel syndrome during pregnancy concomitant with an anomaly of ulnar nerve is described. a 29-year-old iranian woman presented with clinical features of guyon's tunnel syndrome (pain and paresthesia in the fifth finger of the left hand and atro...

AIM The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR. MATERIAL AND METHODS Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literatur...

We contrast the spatial mismatch hypothesis with what we term the racial mismatch hypothesis - that the problem is not a lack of jobs, per se, where blacks live, but a lack of jobs where blacks live into which blacks are hired. We first report new evidence on the spatial mismatch hypothesis, using data from Census Long-Form respondents. We construct direct measures of the presence of jobs in de...

in this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in abaqus software and the modified colliding bodies optimization (mcbo) algorithm implemented in matlab environment. this approach is then employed to study the influence of variable geometrical and geo-mechan...

conclusion the anterior tarsal tunnel syndrome is a known disease. a high index of clinical suspicion is required while dealing with the chronic cases. a detailed history to rule out any traumatic event is necessary too. timely investigations and surgical release give dramatic relief. case presentation a 40 -year-old male patient was presented with the history of persistent pain along the dorsa...

How to make IPv4 users utilize IPv6 applications is a typical scenario of the IPv4/IPv6 inter-operation. Nowadays, Tunnel Broker and 6to4 tunnel mechanisms are the popular solutions for this problem. This paper proposes a multihoming based algorithm MI46 to integrate Tunnel Broker and 6to4 tunnel mechanism. It overcomes the shortcomings of both Tunnel Broker and the 6to4 tunnel mechanism to for...

The boundary element technique is a practical problem-solving tool and useful in comparison to other currently popular alternatives. In this paper, a circular tunnel of a diameter 3.4 m is to be excavated through a clayey soil and surrounded by concrete lining of a thickness 0.2 m, so the clear internal diameter is 3.0 m. A plane strain analysis is adopted for such problem and the soil is assum...

In this thesis innovative tunnel devices based on new architectures, new fabrication approaches and novel material combinations are fabricated and investigated in detail. In particular, nanowire homoand heterojunction tunnel diodes based on Si and InAs-Si have been demonstrated for the rst time. The gained knowledge and understanding of tunnel diodes is applied to design and fabricate InAs-Si h...
